Justin Timberlake and Jessica Biel have remained super friendly since their breakup. But after months of speculation about whether they're together again, it's looking like they're definitely a couple -- even if they won't admit it.
The on-again, off-again duo attended the premiere of Timberlake's new movie In Time together on Thursday night and were spotted being romantic at the after-party, People reports.
Although they weren't all over each other the whole night -- Timberlake, 30, was greeting guests and Biel, 29, stuck close to a group of friends -- things reportedly heated up once most of the invitees had exited the party.
"[They] became more and more affectionate, sneaking kisses, whispering to each other, and sharing quick back rubs and caresses," the onlooker tells People. "At one point, she pretended to punch him a couple times and he gamely bounced up and down like a jack in the box."
Timberlake's In Time costars, Olivia Wilde (who plays his mother) and Amanda Seyfried (his onscreen love interest), were also on hand dancing and celebrating their new futuristic thriller.
As for JT and JB, they may not decide to have their reps confirm their relationship, but sometimes actions speak louder than words.
