American songstress Nicole Scherzinger has distanced herself from reports that she and boyfriend Lewis Hamilton are having relationship troubles.

The X Factor judge is believed to have had crisis talks with her Formula 1-racing beau following reports that she had kissed singer Chris Brown during a break from the Stevenage-born driver.

"Me and my lovely man are lovely, that's what's going on," Scherzinger said this morning on Lorraine. "Yeah, we're great.

"Everything's good and I wish that I could be with him this week and for Japan - I'm used to going to those races with him there.

"I do have something else, our first live show on Saturday, but I think after Korea he will come back and stay with me. So he's actually going to try and be with me as much as possible, so that will be lovely."

Meanwhile, Hamilton is due to switch to Mercedes from McLaren at the end of the season after penning a three-year deal.
