In April, Hoult was rumored to be dating "Glee" star Dianna Agron, after the two were reportedly spotted together in a London pub. That same month, Lawrence reportedly reconnected with Coldplay frontman Chris Martin, after their rumored split in October 2014. 

Good to see they can remain friends. Maybe they'll even go on a double date with their new special someones.

Maybe not.
