Taylor Swift and One Direction's Harry Styles split over a year ago, and it seems like it was a pretty bitter breakup, even though they only dated for a few months. Have they finally buried the hatchet? Perhaps.

Things have remained steadily chilly between the singers whenever they've crossed paths at music industry events since the January 2013 breakup. However, the two (who were briefly and formerly known as "Haylor"), were seen having what appeared to be a "civil conversation" at a pre-Oscars bash this weekend (March 1).

Swift and Styles both attended the party thrown by the Weinstein Company at the Montrose Hotel in Beverly Hills. Swift looked absolutely banging with her custard-colored lace frock and newly-shorn locks, which made us think that Hazza might have been eating his heart out a little.

The former couple was seated at different tables, but a witness saw them engaged in polite conversation, saying, "They looked totally fine considering all their history."

Well, it has been over a year. Maybe the frost has melted and they've moved past the heartache. 'Bout time.

Swift's song 'Sweeter Than Fiction' from the Weinstein film 'One Chance' played through the night, and Hazza, who sported Burberry, was seen in the company of some movie execs.
