Real life couple Leighton Meester and Adam Brody are set to star in their second film together titled Life Partners.

27-year-old Meester and 33-year-old Brody first appeared in The Oranges together in 2011, and now according to Deadline, the couple will appear in Life Partners together as well.

The film is a comedy about two friends, Paige (Gillian Jacobs) and her lesbian friend Sasha (Meester). Paige vows not to get married until Sasha can legally get married as well, which becomes difficult when she meets Tim (Brody), a young doctor.

Us Weekly reported that the couple were secretly dating back in February, a source stating that "They were always close and friendly," adding that they would sometimes "hang out" while filming The Oranges.

Another source stated, "They're a really cute couple. They've been circling around in similar circles for years."

Both Brody and Meester have dated other costars in the past, Brody dating his The OC costar Rachel Bilson until 2006 and Meester dating her Gossip Girl costar Sebastian Stan until 2010.
