Scarlett Johansson breaks up with Nate Naylor

Scarlett Johansson has broken up with her boyfriend Nate Naylor.

Scarlett Johansson, 27, met the dashing advertising executive in January – after splitting up with 52-year-old actor Sean Penn – and the romance progressed quickly, with Nate Naylor, 38, all but moving into her Manhattan apartment.

But last month she was pictured cuddling up to and holding hands with her ex-boyfriend, actor Jared Leto, 40, during a speech at a political rally in North Carolina.

At the time Scarlett Johansson insisted they were just good friends and her representatives adamantly denied that she and Nate Naylor had split, saying: “Scarlett is still dating Nate. This is very innocent. Scarlett and Jared have remained friends, nothing more, nothing less.”

But just a few weeks later Nate Naylor – who is a dead ringer for Don Draper from the TV series Mad Men and who has posted hundreds of violent and sexually charged bondage photographs on his personal website – has moved all of his belongings out of her flat and the relationship is over.

“They never officially lived together, but Nate has moved all of his stuff out and back into his apartment,” says a source.

“The relationship is over. It has not been amicable.”

Scarlett Johansson’s representative declined to comment last night.
