Looks like Justin Timberlake and Jessica Biel are back together. At least, that's what the pair have been hinting at in recent weeks.

The latest occurred on Thursday, when the two were spotted getting close at the after party for the Los Angeles premiere of Timberlake's new film, In Time.

[They] became more and more affectionate, sneaking kisses, whispering to each to each other, and sharing quick back rubs and caresses . . . at one point, she pretended to punch him a couple times and he gamely bounced up and down like a jack in the box, a source told People.

Timberlake, 30, and Biel, 29, reportedly hung out at the party until late, and were one of the last ones to leave.

Earlier this week, the possibly on-again couple were spotted leaving a restaurant in L.A. with Timberlake's parents.

In March, Timberlake and Biel made headlines when a rep for the stars confirmed their break-up.

Addressing the media speculation regarding Jessica Biel and Justin Timberlake's relationship, we are confirming that they mutually have decided to part ways. The two remain friends and continue to hold the highest level of love and respect for each other, according to the spokesperson.

Timberlake, whose previous flames have included Cameron Diaz, Alyssa Milano and of course, Britney Spears, was first romantically linked to Biel in 2007, after being photographed snowboarding together during that year's Sundance Film Festival.

In August, Timberlake and Biel were photographed biking around in Toronto, Canada. The friendly bike ride was followed by another sighting, this time in Colorado in early September, reportedly for Biel's friend's wedding.

There was plenty of P.D.A., and they seemed happy, a source told People at the time.

And during Timberlake's golf charity event in Las Vegas, Biel glammed up and dined with the former NSYNC singer, before driving off together.

Fans and gossipmongers might have to wait until the New York premiere of In Time to see if Biel will show up to support her main squeeze again. Or they'll have to wait until December, when Biel's star-studded film, New Year's Eve comes out.

So are Justin Timberlake and Jessica Biel back together? Here's a photo tribute to the possibly on-again couple.
