Gossip Girl star Leighton Meester has found love with Drew Barrymore's ex-boyfriend Justin Long, according to a new report.

Meester split from her Gossip Girl co-star Sebastian Stan last year and has now sparked speculation of a budding romance with Long after they enjoyed a date in Hollywood on Sunday.

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.
