Luisa offered up the challenge in an interview with this week's Zoo magazine, which also features a series of saucy snaps of the 'Apprentice' runner-up in her smalls.
She told the lads' mag: “Apparently Helen Flanagan had the nerve to say that I’m not classy.
"She’s got some f**king front, that girl. Every time I see a picture of her, her tits are out.
"Don’t get me wrong – I’ve got no problem with that – but mine are better than hers anyway. They’re the best five grand I ever spent! Maybe we should have a boob-off.”
And the star also revealed she had a bit of a soft spot for her 'Celebrity Big Brother' housemate, Dappy after errrrm, getting an eyeful of what he kept in his trousers.
“I did fancy Dappy a little bit," she admitted. "He’s cute. I can also confirm his p*nis is comparable to a magnum of Dom Perignon!
"We didn’t get it on, but I did once accidentally see it in the toilet mirror. And yes, it is the biggest I’ve seen! He’s weirdly shy about it, actually.”
And Dappy, as we know, wasn't the only 'CBB' housemate who caught her eye, but we had no idea just how far she went with Jasmine Waltz in the house - until now.
“I was the most sexually naughty, she said. "I don’t think they showed a lot of what I did with Jasmine. I don’t think they could.
"We made a bed away from the cameras and the microphones and we did some… stuff. We’ve seen each other naked, put it that way.
"She is seriously hot – stupidly good looking – and I’ve kissed her quite a few times. Obviously I’d have a threesome with her, but you can’t beat a man at the end of the day, can you?”
She added: “Because I’m the way I am, I think I allowed other people to be raunchy. After two days in there, I was going stir crazy.
"The boys kept going into the shower to crack one out. I actually walked in on one of them. Everyone was at it! I did have a go at it in the shower myself, but I can’t climax standing up.
"Being in the house for three and a half weeks was very sexually frustrating, believe me. But I’m alright now – I’ve been sorted out since then!”
