Lindsay Lohan has dismissed rumours she's pumped up her pout with cosmetic surgery - posting a picture on the internet to prove her lips are all natural.
The Mean Girls star was rumoured to have enlisted the help of doctors to improve her smile with injectable fillers, after she was spotted with what looked like a cut on her top lip.
But Lohan is adamant she's not undergone any cosmetic procedures - and she's posted a close-up image of her mouth on her Twitter.com page in a bid to prove her point.
In a post on the website, she writes, "Tabloids are lies. Why are all of my friends asking me if I have a cut on my lip? Lol (laugh out loud) coz I don't (sic). See! My lips are just as they've always been. It's nuts that I feel the need to give proof! What is this world coming to."
