Did Mila Kunis Really Break Up Jessica and Justin Timberlake?

Last week we told you Justin Timberlake and Mila Kunis were "flirting," drawing lots of speculation over the weekend that she was, in fact, the cause for J.T. breaking up with Jessica Biel.
So what's the latest? Since Justin's a free man are he and Mila ready to take their flirtship to the next level?

Sources very close to the Black Swan beauty insist not yet.
"They aren't dating," dishes a close chum of Mila's.
Still, pals close to Justin 'fess he's very much interested, while some other J.T. campers are taking pains to let everybody know nothing's technically going on between Mila and Justin.
Jeez, why all the fuss over this potential hotness duo, huh? People break up. They move on. It's natural!
And the fact that these two have been batting eyelashes at one another really shouldn't come as a surprise.
As we told you back in January the Friends With Benefits costars hung tight all through the SAG Awards and late into the night at the after-party at The Sunset Tower hotel.
No Biel in sight.
It will certainly be interesting to see if Mila decides to go for the hunky actor/singer.
Remember, back when Jake Gyllenhaal was doing his best to court the brunette hottie, friends of hers told us she wasn't interested because he was "too Hollywood."
Certainly makes sense, since her long relationship was out of the limelight with Macaulay Culkin.
Regardless, the speculation with Kunis and Timberlake certainly isn't hurting promotion for their upcoming flick.
They have a big press tour coming up so we have a feeling that will tip their "friendship" one way or the other.
Are you rooting for Mila and Justin to hookup? We say, hell yeah!
