A source close to the couple tells the mag:
“They just found out and are incredibly excited. It’s still early, so they are only telling close friends and family members. Megan has become a great stepmom, and Brian knows she’ll be wonderful with the baby. She has really grown in the past couple of years. Megan used to only be concerned with her career, but now family comes first.”
Brian has a 10-year-old son, Kassius, with ex Vanessa Marcil.
This issue of Star magazine hits newsstands this Thursday.
Megan and Brian were just in the news this week after being sued for allegedly attacking a photographer on the beach in Hawaii.
