Shia LaBeouf is really enjoying the fact that he’s finally able to share to the world that he banged Megan Fox (how many guys get to say that?), but Megan and her husband Brian Austin Green are naturally totally P.O.-ed that he blabbed the news. 

A source explains in OK! magazine that Shia’s revelation “really upset” Megan and Brian. “They went through an incredibly rocky period when she and Shia were filming Transformers: Revenge of the Fallen…having Shia run his mouth now and brag about sleeping with Megan is awful for them.”

Though the married couple admit that “technically” Megan isn’t a horrible, cheating ho because they were on a break from their relationship, “they are still so angry at Shia.”

Blah. I really don’t think Megan Fox should be talking. It’s not like she has the greatest filter in the world. Transformers sh!t-talking, anyone?
