NFL superstar quarterback Peyton Manning and his wife Ashley Manning are the proud new parents of twins, RadarOnline.com has learned.

The 35-year-old Indianapolis Colts signal-caller and his wife welcomed their son Marshall Williams Manning and daughter Mosley Thompson Manning on March 31, 2011 in Indianapolis, Indiana. The couple had kept the pregnancy under wraps, as Ashley is regarded as being extremely private.

A family source told RadarOnline.com: “It is true, it is happy news for them.”

These are the couple’s first children.
