Brody and Meester 'secretly dating'
Gossip Girl actress Leighton and former The OC star Adam have been secretly dating for weeks, according to Us magazine.
A source told the mag that the pair - who starred alongside each other in the 2011 film The Oranges - were "always close and friendly" and have been "hanging out".
The new couple - who are said to be keen to keep their romance out of the spotlight - reportedly travelled to Bangkok earlier this year and attended an art exhibition at the Los Angeles County Museum of Art on February 1.
Leighton previously dated actor Aaron Himelstein while Adam dated The OC co-star Rachel Bilson for three years.
