Justin Timberlake HAS cheated on girlfriend Cameron Diaz.

EXCLUSIVE: Bad news for Cameron as sexy model Lucy reveals lover's secret fling
Trousersnake did dirty on Diaz

 

IT'S official!  

The singer spent TWO sizzling nights with leggy Lara Croft double Lucy Clarkson—his "classy" Brit on the side while he was in London.

And the 22-year-old model confirmed that the only undersized feature of the man dubbed Trousersnake was his LIPS.

Lucy told the News of the World: "I was impressed. He's bigger than average and I was overwhelmed. But I didn't really like kissing him because his lips were too small."

Justin pursued Lucy after spotting her picture in a magazine. After meeting for drinks the couple swapped phone numbers and within weeks the model invited him to her flat for some house-your-father.

And as the Rock Your Body singer pawed at her ample curves the last thing on his mind was gorgeous actress Cameron, 5,000 miles away in Los Angeles.

Lucy 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 has wrongly been linked to magic man David Blaine in the past—invited Justin to her Earl's Court flat during the singer's UK tour in January.

Almost as soon as he arrived, the couple disappeared into Lucy's bedroom where she stunned him with her natural 32DD curves.

Cleavage

Lucy, who was spotted by fashion designer Vivienne Westwood when she was 15, revealed: "Justin was totally obsessed with my boobs. He asked if they were false and I replied, ‘Touch them'.

"He grabbed my boobs and pulled them out from the bra. He touched them in such a sensitive way it was like we'd been together for ever. He was just grabbing them and looking at them.

"Justin told me that none of his girlfriends have ever had boobs. He said that he's quite a boob person. He doesn't like them too big or false, but he loves women with cleavage."

Buoyed by the fact that her breasts were the best, Lucy decided to keep the transfixed star wanting more.

She said: "I knew I wanted to do something with him. I wasn't having him around my flat to not do anything, but I couldn't believe I was doing it with a star like Justin.

"I could see that he was totally aroused by what was happening. And although I wanted to make love to Justin, I felt that if I slept with him that would be it— finished, gone, laughable."

Deflated, Justin left Lucy's flat to return to his hotel but, ever the gentleman, he sent her a text saying, "Thank you for being so nice. J x". But there was more to come...

Following a party to celebrate his final UK show, Justin had his drummer, Fish, call the model and summon her to the upmarket Landmark Hotel.

Lucy didn't need to be asked twice and, racing to his room, the pair got straight down to business. After some heavy petting on Justin's king-size bed, Lucy then nipped to the bathroom to check her make-up—and ditch her knickers.

"When I walked into his room, Justin was standing there in a cream-coloured puffa coat and jeans," said Lucy. "I'd had a drink and there was no way I was going to be shy.

"We got to it on the bed then I went to the bathroom to check my make-up, but Justin was urging me back to the bedroom. I slipped off my G-string, left it in the bathroom and walked back into the room with my dress around my waist.

"I told Justin my knickers were off and he pulled me closer, laid me back on the bed and began kissing me from my neck, across my breasts and down to below my navel.

"I took his T-shirt off and that's when I saw his naked chest for the first time.

"Then I glanced down at his jeans which were unbuttoned at the top and I realised he had no underwear on either...great minds think alike!"

As the couple got steamy Lucy believed this would be the night she would have full sex with pop's most sought after man—but at the last minute Justin bottled it when he realised they had no condoms.

Lucy explained: "I kept saying to him that I wasn't ready and he kept asking me why. I told him we didn't have condoms. But it was obvious he was desperate to make love.

"When you're sleeping with Justin Timberlake everything's running through your head. I was imagining how he'd do it and my legs were shaking because I knew what was going to happen. Then he panicked and stopped, saying he couldn't go through with sex. I know I said I wouldn't have made love without protection but at that point I would have gone the whole way, easy.

"I think Justin was close too but he was worried about me getting pregnant.

"He lay back and I told him that I respected his decision."

After that night, Lucy never heard from Justin (pictured right with Cameron) again—but still has fond memories of their brief fling.

She said: "To this day I still look at my bedroom and can't believe Justin's lain on my bed. 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 know Justin and he'd be the perfect boyfriend. But I'd never put him and Cameron together. She comes across as a bit of a nutter."
