After we snapped Jessica Biel flirting with her A-Team co-star Bradley Cooper, many began to speculate that the Hangover star was the reason behind Biel's split from longtime boyfriend Justin Timberlake. However, it seems as though Justin may have already moved on from Jessica when he started shooting Friends With Benefits with brunette bombshell Mila Kunis!

Justin raised eyebrows when brought his mom to the Oscars instead of Jessica, and witnesses noticed the former boy bander looking totally smitten with the Black Swan beauty at the ceremony. "Justin is very interested in Mila," a source close to Kunis tells E! Online. "They've been flirting, but so far nothing has happened." Justin revealed that shooting sex scenes with Kunis was a breeze, telling Marc Malkin, "I think I could speak for all the men in the world when I say that's the easy part."

So are Jessica and Bradley an item now? We haven't seen his rumored lady love Renee Zellweger in a while, and it seems like JT and Mila are headed down lovers lane as well!
