We're not entirely sure, but we like to think it's kissing...

Erm, hello Sarah Harding and Marvin JLS - what do you think you're up to? And does Sarah's live-in-lover Tom know about it?

We think he probably does, in fact he was probably there, but we're just going to ignore that and be all immature and make out that they're soooo GETTING. IT. ON.

Last night Sarah enjoyed a yummy, scrummy dinner at Texture Restaurant in Marble Arch (which, incidentally, is right next to Sugarscape - how come we didn't spot them? Because we can't afford to eat in fancy restaurants? Oh, alrighty then) with JLS hottie Marvin Hume before heading to Mahiki Nightclub.

THEY'RE SO GETTING IT ON. Amazing. (And if they're not, please don't spoil our fun.)
