Meester split from her Gossip Girl co-star Sebastian Stan last year (10) and has now sparked speculation of a budding romance with Long after they enjoyed a date in Hollywood on Sunday (15May11).
The new couple shared a romantic dinner at French bistro La Poubelle, where they stayed past midnight. They were also spotted holding hands outside the restaurant.
And the stars weren’t shy about being seen together – an onlooker tells People.com, “They were happily willing to talk to fans who approached them.”
Long’s on/off romance with Barrymore ended in 2008, but they remained friends and went on to star as lovers in the 2010 comedy Going the Distance.
