Oscar-winning actress Brie Larson has split up with her fiance, Phantom Planet frontman Alex Greenwald.

Larson, 29, and Greenwald, 39, were a couple for more than five years, announcing their engagement in May 2016.

But E! News said Friday they recently called off their wedding plans.

"They have taken a step back from their engagement for the time being but they remain close," People.com quoted an unnamed source as saying.

No reason for the breakup was reported.
