Scherzinger and Hamilton hold `crisis talks` over Chris Brown `kiss` pics

London - Formula 1 ace Lewis Hamilton and X Factor judge Nicole Scherzinger have had crisis talks to save their on-off relationship after pictures emerged of her partying with Chris Brown.

Chris and the Nicole were spotted looking intimate and appeared to be locking lips at exclusive Los Angeles night spot Supperclub last month, but the pair insisted they were simply talking.

The Sun has now reported that Hamilton had called time on their romance three weeks ago but "hit the roof" after seeing the snaps.

He is then thought to have had a change of heart regarding their relationship and is convinced that what he has with Nicole is worth saving.

“Splitting was his decision. He’s got a lot on his plate at the moment. And her commitments on X Factor and his career were clashing over the last few months,” a source told the publication.

“When he saw the pictures of her with Chris, he flew off the handle. He wasn’t happy at all - even though they were not together any more.”

Singer Nicole, 34, had already publicly explained that she was old friends with Rihanna’s violent ex and had merely been trying to chat in a noisy Hollywood nightclub.

But the former world champion wanted to have a one-on-one chat with the glamorous 'X Factor' UK judge.

“Lewis wanted to hear it for himself. Nicole returned to Britain yesterday, tweeting: Guess who just moved to London! 6am and I’ve just touched down. Let’s play ball UK,” the source said.
