Eat your vitamins and say your prayers brothers ... 'cause TMZ has learned Brooke Hogan is officially single again.
Sources close to Brooke tell us Hulk's daughter ended her engagement to Dallas Cowboys center Phil Costa a few weeks ago ... after he proposed in Vegas back in June.
We're told Brooke realized things had moved way too fast, too soon ... so she decided to call it quits and focus on her music -- before making things official forever.
Our sources say Hogan recently moved back to L.A. to put the finishing touches on her new album ... and she wanted to be closer to Momma Hogan.
Brooke posted this ringless photo a few days ago.
Looks like she won't have much trouble finding a rebound dude.
