You can see her on Saturday-morning kids' TV - she's the one in a (frankly way too small) school uniform and covered in custard. Call us old-fashioned, but we thought the 24-year-old presenter might look even better in suspenders...

It's not that we're shallow. Intelligence, sharp wit and professional success remain key criteria for potential recipients of Arena love. It's just that we also rate flirtatiousness, beautiful womanly proportions (none of your fragile little dolls or straight-up-and-dow models here), saucer eyes, a dirty laugh and great dollops of grown-up sex appeal.
So why exactly, when she's the proud owner of all of the above, are we feeling guilty about our fast developing obsession with 24-year-old British TV presenter Holly Willoughby?
Perhaps only because she hasn't yet graduated from the confines of the testing lab that is children's TV - fronting ITV's MOM on a Saturday morning, as well as her own early evening show, Feel The Fear and fill-in stints on CD:UK. But graduate she will. And Arena will be there applauding proudly in the front row.
If we're honest, it's not the guilt that's keeping Arena awake at night - these Fifties pin-up images of HW trussed up in vintage corsets, stockings, suspenders and f*ck-me heels are doing that all on there own.
Despite being a highly successful teen model, Home Counties Holly (born and raised in Sussex) remains gloriously glued down to earth, attributable in part to the fact she didn't jump directly from underwear ads to TV stardom, but took in being a student receptionist, barmaid, backpacker and cleaner in the years in-between. So while she plays the knowing glam-puss to fellow presenter-going-places Fearne Cotton's ingenue rock chick - she's also happy being glam-puss with custard pie on her face (you'll note Saturday morning TV hasn't changed so much over the year).
One final thing: being morally upstanding types, the last criterion on our Ms Arena suitability checklist is that she's single. So, over an extended lunch largely transfixed by her luscious lips, we broach the subject of Holly's current romantic status. "Single," she replies. That sound of triumphant scratching is another box being ticked for Ms Willoughby. "As in I don't have a boyfriend, but I do go on dates and see different people." More furious ticking. Things are looking up all-round!

You looked liked you enjoyed glamming up for Arena?
I loved the shoot. I've never seen myself look like this! I normally wear lots of black eyeliner and bright lipstick, whereas for these photos the make-up was quite clean and simple. It's quite weird realising it was me.

As a teenage model, you obviously did plenty of shoots. How different was it now you're are grown up?
Well, when I first modeled I didn't have boobs at all. Now I'm more confident with myself and my body and with people seeing it.

So you're happy with the idea of being seen as a sex symbol ?
Absolutely. I mean, the reason women spend hours buying new make-up is because they want to put across an image that attracts boys. I love boys, I love talking to boys, I love flirting with boys. So yes, I feel happy that these pictures make me look sexy.

In the course of out extensive research, Arena noticed there is a section in MOM where you dress up in school uniform - with a number of shirt buttons undone - and partake in a food fight. Do you realise that there might be men watching who get off on this? (Though not Arena, obviously...)
When I was at school, having a food fight was something I wanted to do every day, so there fore doing it dressed in school uniform isn't unreasonable. But of course I know the connotations of me as a grown adult dressed in school uniform. So yes, I am aware of how that looks.

Have you ever had anyone on your show that you idolised?
We had Simon le Non on CD:UK and I was like, "Oh my God." I didn't know where to look.

Isn't he a bit old for you?
Yeah, but he was the first boy I know that girls fancied , so to then meet him and interview him was pretty amazing.

Did he get stuck in or was he a bit aloof?
He's Simon le Bon, he's a notorious flirt!

Ask you out did he?
No he did not. No guest has ever tried it on, but I'm actually hoping that it will happen.

It always seems to be happening to your mate Fearne Cotton...
I know, lucky old Fearne! Maybe it's because on MOM you're getting involved and running around, rather than doing glamorous and sexy things. I have to wear a cape and an awful blonde wig and scream, so guests just don't fancy me.

You poor thing. What's the worst thing that's happened to you on air?
There's something that hasn't actually been screened yet. I was on that Celebrities Under Pressure Program with Vernon Kay where a celebrity lives with a family for three days and if you win a challenge the family wins money. I had to get these ping-pong balls through five holes cut out of a ping-pong table in a minuet. I practiced for about three weeks beforehand and could do it perfectly, there was no way I was going to lose it. But when we filmed I just couldn't do it. It was awful and no one knew what to say. Then there was also the incident when I was dancing (on MOM) and I wasn't wearing a bra and... It was all very embarrassing.

Very Tara Reid. But it begs the question, why were you sans brassiere?
I don't know, I will never do it again, though. You learn from your mistakes, my mum gave me a hard time about that.

In your position, do you ever get away with behaving badly?
I'm not squeaky clean, it's not like I stay in every night reading. Of course I go out occasionally, and sometimes I even drink too much. But that's all. I don't think people mind that; there would only be a problem if suddenly there was a massive drugs story about me, which would make people question my role as a kids' TV presenter. And I can totally understand that.

So if cocaine binges are out, what do you do the night before the program?
Most of our guests come down on the Friday for rehearsals. One of the most amusing nights was when I came back to the hotel bar and Blazin' Squad were all sat around. I thought "I wonder if they'll be up late". But they all had one shot of Baileys and went straight to bed which made me cry with laughter.

What's the one thing you bought when you got your first decent pay cheque?
An amazing Chloe dress to wear to The Brits, which cost me about £1,000. It had all these tiny straps holding it up, and when I was leaving to go home I suddenly realised they'd all broken apart from one, so there was just one strap holding the whole thing up. I took it back and exchanged it for something else - and I'd already worn it for the event, so it worked out quite well!

Any particular fashion obsessions?
It was shoes, though my shoe obsession is starting to diminish; I've only worn Converse and cowboy boots in the last year. I'm starting to get a bit of a jewellery obsession now though. And I do have a ridiculous underwear habit - expensive and cheap. I did buy myself some Agent Provocateur as a treat. And I always wear matching sets.

Good to know. Do you mind being held up as an icon of womanly appeal as apposed to being super-skinny?
Not at all. I like it when people say I have a womanly figure. I'm not going to lie and say I'm absolutely happy with my figure, of course I'd like my bum to be a little firmer, sometimes I'd like to be able to wear certain things that I can't. But I think from what I've worked out, people tend to preferred it; men do like having something to hold on to.

Do you have a guilty pleasure?
Cheese. I love it, I could eat slabs of cheese all day long.

Favorite variety?
Anything - chedder, Kraft slices, Camembert. I don't like goats' cheese though, that's the only one.

We'll bear that in mind. When was your last big crazy night out?
The most recent Glastonbury. It was the best weekend of my life. I got down there on Saturday afternoon so I missed all the shit weather. I saw the Magic Numbers and then Coldplay and then spent the whole night in the Lost Vagueness tent and watched the sun come up in Green Fields.

Finally, should we cancel Third World Debt?
That's a very tricky question. In an ideal situation, yes. But it's never that simple, is it?
