Scarlett Johansson and Nate Naylor Break Up: Avengers Hottie Splits with Ad Executive Boyfriend

Reports have it that actress Scarlett Johansson has officially broken up with her New York City ad executive boyfriend Nate Naylor. Sources claim that the split was pretty nasty, and that Naylor has already moved all of his possessions back into his own apartment.

27-year-old Johansson publically announced that she was dating Naylor in the May issue of Vogue magazine, although the two were spotted holding hands on the streets of New York City sometime last January. But now it looks like their 10-month courtship is officially over.

"They never officially lived together, but Nate has moved all of his stuff out and back into his apartment. The relationship is over. It has not been amicable," a source close to the "Avengers" hottie tells the Inquisitr.com.

Another source admits to People, "She broke up with him last week," one source who knows both parties tells PEOPLE. "He's pretty upset but the writing was on the wall. A lot of people were surprised it lasted this long."

Rumors insist that the couple had been struggling with their relationship since the summer, although Johansson's rep denied it, stating in September: "Scarlett is still dating Nate. This is very innocent. Scarlett and Jared have remained friends, nothing more, nothing less." Johansson was spotted at the Democratic National Convention holding hands with her former ex- Jared Leto earlier that month, sparking rumors that Naylor would soon be out of the picture.

Johansson's rep has yet to speak on the break up.
