Patrick Dempsey Gives Pregnant Co-Star Advice

Actor Patrick Dempsey has some advice for his "Made of Honor" co-star Michelle Monaghan. The actress is pregnant with her first child.

Dempsey said he knew about the pregnancy before Monaghan went public with the news. According to People.com, the "Grey's Anatomy" actor said, "It was a big secret, and I wasn't allowed to tell anyone, but I knew Michelle was pregnant, and I am thrilled for her. She will be a great mom because she has a good head on her shoulders, a fine husband, and overall, she is a lovely woman."

Dempsey, 42, is racing this weekend in the Six Hours of the Glen Grand-Am Rolex Sports Car Series at Watkins Glen International in upstate New York. Dempsey and his wife Jillian, have twin 18-month-old sons, Darby and Sullivan, and a 6-year-old daughter Talula.

Dempsey's advice to Monaghan: "I told Michelle she may not see it now, but her life will change profoundly after she delivers the baby," he said. "I told her being a parent is a feeling that she will not understand until she actually has the child."
