The couple became an item back in 2004. They met on the set of Hope and Faith — she was 18, and he was 30. They got engaged in 2006, broke the engagement in 2009, got back together in 2010, and were married that June in Hawaii.

Noah arrived on September 27, 2012. After two weeks of secrecy, Megan took to Facebook to announce the birth: "We are humbled to have the opportunity to call ourselves the parents of this beautiful soul, and I am forever grateful to God for allowing me to know this boundless, immaculate love. Thanks to those of you who wish to send your positive energy and well-wishes."

Megan's now in NYC filming Teenage Mutant Ninja Turtles. She plays the role of reporter April O'Neill.
