Bradley Cooper and Zoe Saldana have reportedly split up.

The 37-year-old actor - who met the 33-year-old beauty last year when they filmed Words - have called time on their three-month romance, friends have revealed.

"They're definitely not together," a source told Us Weekly.

However, despite the split, Zoe - who was pictured hanging out with the actor's mother Gloria last month - is said not to be too upset about her romance with Bradley coming to an end. "She and Bradley weren't super-serious at all," another source said.

Hangover actor Bradley recently admitted romancing a fellow celebrity can be more trouble-free as they understand life in the spotlight: "Connection and chemistry are amazing things and if the other person is used to being in the media, it makes things easier."
