Bradley Cooper's romance with Zoe Saldana is back on. The Hangover actor was spotted leaving Zoe's Hollywood home in the early hours of Saturday morning.

The on-off couple met up again later yesterday for a cosy cinema date at the Arclight Dome Theater on Sunset Boulevard, where they watched the controversial new Scientology-inspired movie The Master.

The former co-stars - whose relationship seemed awkward at the premiere of The Words earlier in September - appear to have rekindled their casual romance after breaking up in March. A source close to the Avatar actress said at the time, "They're definitely not together. She and Bradley weren't super-serious at all."
