Leighton Meester is dating Adam Brody.
The couple – who co-starred in 2011 romantic-comedy movie ‘The Oranges’ – have reportedly been secretly seeing each other for several weeks, which comes after they used to "hang out" together while shooting the film.
An insider confirmed to Us Weekly: "They were always close and friendly."
The 26-year-old beauty – who is known for her role as Blair Waldorf in teen drama TV series ‘Gossip Girl’ – and the 33-year-old actor were spotted "hugging and laughing" as they took in art exhibitions at the Los Angeles County Museum of Art earlier this month.
One eyewitness, @CedricDiggory, wrote on Twitter: "They were getting cuddly today at the LACMA apparently? Hugging & laughing. (sic)"
@tayeschbach19 tweeted: "Just in the same museum exhibit with Adam Brody and leighton meester. Enough said. #lacelebsiting (sic)"
Leighton and Adam – who starred as Seth Cohen in US teen drama TV series ‘The O.C.’ for four years – also travelled to Bangkok together earlier this year where they were spotted at the Siam Kempinski Hotel in the Thai capital city.
Adam was recently linked to 34-year-old director Lorene Scafaria – who helmed Steve Carell and Keira Knightley’s comedy-drama movie ‘Seeking a Friend for the End of the World’ – while Leighton has previously dated ‘Austin Powers’ actor Aaron Himelstein.
