UK- Justin Timberlake reportedly cheated on Cameron Diaz with a Lara Croft look-a-like, it has been claimed.

British model Lucy Clarkson alleges she spent two nights of passion with the pop heartthrob while he was touring the UK in January.

But despite reported heavy petting in Lucy’s London flat and Justin’s hotel room, the brunette beauty claims they didn’t have full sex – because they didn’t have any contraception. Recalling their second night together, she told Britain’s News of the World newspaper: “I kept saying I wasn’t ready because we didn’t have any condoms.

But it was obvious he was desperate to make love. “Then he panicked and stopped, saying he couldn’t go through with sex.

“I think he was worried about me getting pregnant.”

Lucy, who says she was “overwhelmed” by the size of Justin’s “bigger than average” manhood, claims Justin only mentioned girlfriend Cameron – who was 5,000 miles away in Los Angeles – once during their time together.

She said: “I never brought up Cameron and it was like she didn’t exist in his heart because he only mentioned her once.

That was when I spilled some of my drink. He said, ‘Cam does that too.'” Lucy, who was wrongly linked to magician David Blaine last month, has also branded Cameron “a nutter” and believes she would have become Justin’s girlfriend if he wasn’t dating the ‘Charlie’s Angels’ beauty.

She said: “I think if Justin wasn’t dating Cameron we would have got it together. When I hear of rifts in their relationship I think they’re strained and he’s under stress. “I’d never put Justin and Cameron together. She comes across as a bit of a nutter.”
