Sources told the mag that living on opposite coasts – Williams resides in NYC and Segel in L.A. – was the cause of the breakup. The long-distance couple decided to go their separate ways a few weeks ago.
The “Oz the Great and Powerful” actress previously told In Style of their relationship, "If people are happy about it that makes me feel good ... Any kind sentiment that the world can feed back, well, I won't turn it down.”
Reps for the actors have yet to comment.
After a year of dating, Michelle Williams and Jason Segel have split, according to People.
