Justin Timberlake "Aggressively Pursuing" Mila Kunis

Justin Timberlake and Mila Kunis on set.
Buzz, Love

Where is JT's girlfriend while he's getting cozy with his co-star?

When we first heard Justin Timberlake and Mila Kunis were getting cozy at the PEOPLE/Entertainment Industry Foundation SAG Gala this past Sunday, we almost signaled for a cute new couple alert.

But then it hit us—Oh, yeah. JT is supposedly taken. Awkward.

It's easy to forget that Justin and Jessica Biel are still an item, considering he's allegedly hooked up with a good portion of Hollywood, everyone from Olivia Munn to a few back-up dancers. Will Mila be the next conquest in the singer-turned-actor's little black book? It's possible. Will Scarlett Johansson Reignite Romance With Justin Timberlake?

The Friends With Benefits co-stars spent most of the night together post-SAG... alone. Which seems pretty couple-ish to us. According to Celebitchy.com, US Weekly reported that Justin was "aggressively pursuing" Mila at the event, and was in a bit of a tizzy when she talked to other guys instead of him. Meanwhile, People said that the two looked "pretty inseparable" at the Weinstein Company party after that.

This is old news to some, as apparently JT was "obsessed" with Mila while they filmed their upcoming rom-com together and has been carrying a torch for her ever since.

“Justin’s always seemed interested in pursuing something with Mila,” claimed a source to US Weekly. Hmm... Interesting.

Is anyone else wondering where Jessica Biel is in all this? For all intents and purposes, she is still Justin's girlfriend. But the hitch is this: They rarely step out in public as a pair, let alone walk red carpets together. And rumors fly around JT's romantic activities in her absence.

But an insider told People that it's still Team Timberlake-Biel all the way. "Justin and Jessica are definitely together," the source insisted. "They're happy in their relationship."

All is well in paradise, eh? Well, if we keep hearing that JT's fooling around behind Jess' back, we're thinking their blissful days may be numbered.
