The former 'Beverly Hills 90210' actor has an eight-year-old son, Kassius, from a previous relationship and admits the stunning actress plays a huge role in the little boy's life.
He told Parade.com: "I'm the daddy and I remind my son that I'm not around just to be his friend. I'm here to steer him in the right direction and teach him lessons that I've learned and help him become a man. I'm totally learning as I go. But, to be honest, Megan has been just so helpful and instrumental in raising him."
Brian and Megan recently took part in a video to attack budget cuts in Los Angeles schools and Brian admits Megan was a huge hit with the kids.
He revealed: "Somebody said, 'Do you think Megan would be interested in doing it?' I said, 'I can answer that without even having to ask her.' It was really cute to watch her with the kids. It would become sort of a parade at times. They'd follow around behind her and say things like, 'You're so pretty.' She wore some everyday thing. But you could wrap her in foil and she'd look hot."
