"I can confirm Megan is expecting her second child with her husband Brian," the 27-year-old's spokesperson told the New York Post.
The pair are already parents to 10-month-old son Noah, while Brian has an 11-year-old boy from a previous relationship with Vanessa Marcil Giovinazzo.
Since giving birth to her first child Megan has spoken of her desire to have more kids. In a recent interview with Marie Claire she said, "All I wanted to do my whole, whole life was have a baby and, now, I've finally done it.
"I just want to give Noah as much of myself as I can. And I want to have more kids. That is where my heart is."
