Rosario Dawson and Danny Boyle have split up.

The 33-year-old Sin City actress - who was recently said to be "deeply in love" with the Oscar-winning Slumdog Millionaire director - has ended their "unlikely" romance.

A friend close to the 56-year-old British moviemaker told the Sunday Telegraph, "It's all over. It's very sad, but they always were an unlikely couple, in many ways."

The couple got together after Danny cast the American beauty in his film Trance last year. Despite their 23-year age gap, the former couple were a great match according to friends and had a lot in common. An insider previously explained, "She's not your typical selfish Hollywood actress. She grew up in a New York squat and Danny's dad was a laborer. Politically, they are on the same page and I guess it doesn't hurt that Danny thinks Rosario is very sexy."
