Jonathan Majors should be on top of the world.

His latest movie Creed 3 is a big hit and he's becoming a household name.

But with fame comes increased scrutiny.

The 33-year old is trending for the wrong reason this afternoon after being arrested in New York City for roughing up a woman described as his girlfriend Friday night.  He was booked late this morning on charges of strangulation, assault, and harassment. 

Sources tell TMZ the GF tried to take a look at his phone because she believed he was communicating with another woman. It was then things got violent.  The GF went to a friend's house after the alleged assault and called the police on Majors the next morning.

Majors' team denies he got rough.
