Nicole Scherzinger Snogs A Man Who Isn't Lewis Hamilton!

What will Lewis Hamilton say about this picture of new X Factor judge Nicole Scherzinger snogging another man?

'Don't Hold Your Breath' singer Nicole Scherzinger performed at a huge iHeartRadio concert in Las Vegas this weekend, and got involved in some tongue action with American Idol judge Steven Tyler.

With talk of rivalry between the pair's talent shows, Nicole and Aerosmith's Steven dispelled the rumours by performing a duet at the show and finished their performance with a kiss.

Former Pussycat Doll Nicole, who has been dating Lewis Hamilton for four years, replaced Cheryl Cole on The X Factor in the US, while Steven Tyler was Simon Cowell's replacement on Idol.

Despite it looking like a full blown snog, it's thought the kiss was purely for fun.
