'Empire' Stars Boo Boo Kitty Hooking Up With Andre Lyon... For Real!

EXCLUSIVE

"Empire" stars Andre Lyon and Anika Calhoun are family on-screen ... but off-screen the actors may be hooking up.

Check out this video of Trai Byers, who plays Andre, and Grace Gealey, the now-famous Boo Boo Kitty. They went to a wedding together and people who went to the reception tell us they were super affectionate at times, but still conscious people were looking.  

The bride and groom -- Lauren Whitney Johnson and Cedric Sanders -- are both actors, but nowhere near as famous as Lucious' oldest son and ex-fiancée.

Andre needs someone new. His wife's a killer.
