Bradley Cooper and Zoe Saldana were forced to reunite on the red carpet at the Hollywood premiere of The Words last night.

The couple - who dated for three months after meeting on the set - have managed to avoid each other at previous screenings for the film, but posed for pictures together after walking the line of journalists separately.

They got together after Star Trek beauty Zoe broke up with her partner of 11 years Keith Britton in November last year. By March the romance was over, although friends say they were never serious about each other. "They're definitely not together. She and Bradley weren't super serious at all," a source said.

The pair are not the only stars to have to reunite on the red carpet after splitting - it is thought Robert Pattinson and Kristen Stewart will be seen together to promote the last film in the Twilight franchise, despite her cheating on him with Snow White and the Huntsman director Rupert Sanders.
