Rochelle's been in the business we call show since the age of 12 but where on the celebometre does she reside? Time to find out...
1. Who's the most famous name in your mobile?
I've got Flo-Rida, JLS and Tulisa.
3/5. Ker-lang! Three for the price of one.
2. Most bizarre thing you've ever read about yourself?
That I was engaged! I'm not.
0/5. Not exactly bizarre.
3. How much is too much for a haircut?
Well we get ours done for nothing but I wouldn't pay any more than the cost of a pair of shoes or a handbag.
3/5. We're guessing she doesn't get her footwear at Primark.
4. Katie Price. Friend or foe?
Well I don't dislike Katie Price. I have met her once a while ago and she was pleasant. She's done alright for herself. There are a lot of girls who are glamour models but she's taken it that one step further and built a whole business around it. What she does personally is nothing to do with me though.
0/5. Cop out. We all know Pricey's personal business is everyone's business.
5. Weirdest thing you've been sent by a fan?
We don't really get weird things. We get nice stuff, like our fans know Vanessa loves Haribo sweets so she gets sent those and I get Ferrero Rocher chocolates.
2/5. 'Cos she's the classy one.
6. Best party ever?
The Cavalli party in this massive warehouse in London. We were loaned some of his dresses for the night so we felt really special.
2/5. Would've scored more if 'loaned' was replaced by 'given'.
7. Ever used your fame to get what you want?
No, but certain friends will be like 'I know Rochelle from The Saturdays, can I get a table please?'
0/5. They seem to have the idea of this showbiz lark more than Rochelle.
8. How much cash would it take to get you to pose in the buff?
I think 'never say never' to these kind of things. Ten years down the line I could be desperate but at the moment there's not going to be any naked posing!
5/5. Full marks for being acutely aware of the fickle nature of fame. And for being shameless.
9. Best freebie you ever received?
A holiday to St. Lucia. I took my mum.
0/5. She giveth with one hand, yet takes away with the other...
10. Ever been chatted up by another celeb?
Yes, Marv [Rochelle's boyfriend, Marvin Humes from JLS] and he had to do a LOT of chasing!
5/5.
Result: 20/50
A low score for Rochelle, despite spending half her life in the glare of the showbiz spotlight. She's got the showbiz chums and the famous boyfriend but is far too grounded to start dishing out any don't-you-know-who-I-ams - she lets her friends do that instead.
