Rumors are surfacing that JT might be a cheater cheater pumpkin eater!

Before Justin Timberlake was married to Jessica Biel it wasn't really a secret that he had a wandering eye. Photos surfaced of him kissing other girls and there was even that whole thing with Olivia Munn. However, Biel agreed to marry Justin (however, she got an AWESOME pre-nup...good for her) as long as he began to live his life with only one woman.

However, Justin was in Rio not that long ago for the Rock in Rio...and things may or may not have got a little heated with Brazilian actress, Thaila Ayala. There really isn't any evidence to prove or disprove the claim. Though, as the saying goes once a cheater...always a cheater.
