Michelle Williams and Jason Segel Split

The Oz the Great and Powerful star and the How I Met Your Mother actor split a few weeks ago after dating for a year, a source confirms to PEOPLE.
The long distance – Williams, 32, is based in New York City, while Segel, 33, primarily resides in Los Angeles – was the reason behind the breakup, the source adds.
Earlier in the month, the actress told In Style that she cherished public support of her 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," she explained.
The couple, who were often seen out and about with 7-year-old Matilda, Williams' daughter with the late Heath Ledger, began staying together in a Brooklyn apartment last fall.
Reps for the actors have not commented.
