Now you see them ... kissing.
Jesse Eisenberg and Mia Wasikowska were photographed in Toronto on Tuesday, their public display of affection going beyond the hand-holding previously seen.
With Eisenberg, 29, in a blue T-shirt and sneakers and Wasikowska covered up in a black long-sleeved top and wide-legged pants, the pair was also snapped strolling the city streets looking very much like a couple in love.
The Oscar-nominated star of The Social Network and most recently Now You See Me costarred with Wasikowska, 23, in The Double, a comedy about a man who is driven insane by the appearance of his doppelgänger.
Eisenberg had been linked to actress Anna Strout.
