Aisleyne Horgan-Wallace is toning down her image to take on the role of ambassador for nightclub project Club4Climate.

The Big Brother 7 finalist said it was time to stop falling out of clubs in skimpy outfits if she wants to act as a role model.

She told Sky Showbiz: "Club4Climate is to raise awareness for younger generations - we need to stand up and do something for our planet. Everyone knows me as a club, party girl, so why not turn it into something good?"

The 28-year-old will tour nightclubs to raise cash for the Clean Planet Trust, which supports emission-reduction projects around the world.

Aisleyne, who is planning an autobiography, also revealed that she admires Angelina Jolie for adopting three children, saying: "I actually want to adopt children as well, but I'm not copying her. It's just something I've always wanted to do. I think she's amazing. It's not all about her, she wants to give back and I think that's so admirable."

Talking about her change of image, she said: "I get fan messages through my website and my manager, and I thought, 'Oh my God. Me coming out of a club with my tits hanging out is not a good look'. If people are looking up to me I've got to stop that."

Aisleyne is also a patron for Brain Tumour UK.
