Adam Brody says Rachel Bilson is ''one of the all time'' greatest kissers.

The 34-year-old actor, who is married to former 'Gossip Girl' star Leighton Meester, opened up about what it was like to kiss his ex-girlfriend on-screen when they co-starred as Seth Cohen and Summer Roberts on 'The O.C.' between 2003 and 2007.

Asked about locking lips with the brunette beauty, whom he dated for three years until late 2006, the 'Oranges' heartthrob told fans in a Reddit 'Ask Me Anything' session yesterday (28.08.14): ''One of the all time greats!''

'Hart of Dixie' star Rachel, 33, is currently expecting her first child with boyfriend Hayden Christensen, and Adam, who married Leighton, 28, in a secret ceremony in February, also hopes to they have a family in the future.

Discussing the number of children they want, he joked: ''I say 12. And I decide.''

The actor praised his wife for keeping their household under control.

He said: ''I do some stuff but she definitely does the heavy lifting (figuratively). Literally, I do the heavy lifting.''

Meanwhile, the heartthrob insists that he is still on good terms with all of his former castmates, including 'Guardians of the Galaxy' star Chris Pratt, who recently accused the stars of 'The O.C.' of taking their success on the show for granted when it was on air.

He said: ''I do not think we were guilty of taking it for granted. I also love Chris and he loves me so shut up!''
