The Capital Late Show With Marvin Humes 10pm - 1am
We love a good popstar smooch and it doesn't get any better than Rihanna and Britney puckering up at the Billboard Awards.
The pair celebrate their performance of 'S&M' with a kiss for the cameras.
It's not the first time Britney's shared a tongue sandwich with a special lady friend. Here she is smooching the face off Madonna.
While it was her kiss with Britney that stole the headlines, many people didn't realise that Christina actually kissed Madonna too during their legendary 2003 VMAs performance.
Katy Perry and Russell Brand, still in honeymoon mode arriving at the Grammy Awards, 2011
Enrique Iglesias makes one fan's night at the Jinglebell Ball.
Okay they're not kissing, but what would you do if you were JT and you had the chance to grab one of the most famous bums in history?
The chances are they were just having a good natter, but how cool would it be if Cheryl was actually snogging Rihanna's ear?
Simon once told a newspaper that if he could snog anyone in the world it would be Cheryl. Presumably he meant anyone after his fiance. *Cough*
