Negating rumors that she’s eyeing a romance with Shia LaBeouf, insiders tell OK! magazine the Miss Fox and her “Beverly Hills 90210” beau are definitely back on as a couple.

“Megan and

Brian are definitely together. They shout each other baby and are just so cute together. I don’t think they ever really broke up,” says the insider. “They’re so comfortable and ridiculously cute. In the elevator Megan put on chapstick with her finger and next put the rest from her finger on his lips. They seem so happy together and so in love.”

The OK! source added, “You would never know she had the biggest movie of the summer out right now considering she was so nice and humble, nearly timid and shy.”
