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.

A source told Us Weekly magazine: ''They're definitely not together.''

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.

Another source said: ''She and Bradley weren't super-serious at all.''

'Hangover' actor Bradley - who split from Renee Zellweger last year and has previously been linked to the likes of Jennifer Lopez and Olivia Wilde - recently admitted romancing a fellow celebrity can be more trouble-free as they understand life in the spotlight.

He said: ''Connection and chemistry are amazing things and if the other person is used to being in the media, it makes things easier.''

In November, Zoe announced she and her fiance of 11 years, Keith Britton, were splitting amicably.
