The NYC premiere of The Five-Year Engagement kicked off this year's Tribeca Film Festival at the Ziegfeld Theatre, so many stars were in town for the big event and after-party.
The flick's leading man, Jason Segel, was spotted cuddling with new love Michelle Williams at the after-party, and co-star Emily Blunt, who looked amazing in a black and green Jason Wu dress, was seen walking arm in arm with her hubby John Krasinksi.
Also on hand, Robert De Niro, Kim Cattrall, Julia Louis-Dreyfus, Olivia Wilde, Camilla Belle and Leelee Sobieski.
Speaking of five year engagements, Leelee thinks waiting years on end is entirely too long.
"I feel like the ideal length is three months," she told OK!. "I go short and sweet on the engagement."
