They enjoyed a short and intense three month romance after falling in love on the set of The Words.
Although no longer together, Bradley Cooper and Zoe Saldana are still professional and comfortable in each other's company.
Both were reunited at the Los Angeles premiere of the film that brought them together.

While working with an ex could potentially be uncomfortable, the actors seemed to have the situation under control.
Zoe's mega-watt smile was outshone only by the spectacular beaded gold number she wore.
By her side, dapper Bradley more than lived up to his title as People magazine's sexiest man alive. The Hollywood heart-throb looked relaxed and happy, placing his arm loosely around Zoe’s waist.
In The Words, the leading man gives a delicate performance as a writer who plagiarises his work on the road to success. On-screen wife Zoe helps him deal with the fall out.
The film also stars Jeremy Irons and Dennis Quaid. Both of the Hollywood veterans were there for the big night too.
