The newlyweds, who had an extra-marital affair after meeting on the set of Northern Lights, reportedly couldn't keep their hands off each other at the NBC party at Del Posto in New York on Monday night, much to the disgust of other guests.
A source told Us Magazine, '[They were] making out in the middle of [everything].
'[Rimes was] making a compete scene and holding up her camera as they are making out so she [could] take pictures of them making out - it was unreal.'
'We were like, 'Who the hell is that?' And of course it was them. It was so beyond ridiculous.'
