DAN MARINO will be a big part of CBS' Super Bowl coverage on Sunday.  But here's something he probably won't talk about:  His LOVE CHILD.  Marino has been married to his wife Claire since 1985.  But late in 2004, he messed around with a production assistant for CBS Sports named Donna Savattere. 

He got her pregnant, and she gave birth to their daughter Chloe in June of 2005.  According to the "New York Post", he paid her MILLIONS to keep it all on the down-low.  (Here's a picture of Donna and Chloe.)  (New York Post)

After all this came out, Marino issued a statement saying, "This is a personal and private matter.  I take full responsibility both personally and financially for my actions now as I did then.  We mutually agreed to keep our arrangement private to protect all parties involved."

He added that his marriage survived the affair, "My wife and I have been married for almost 30 years and have six children together.  And we continue to be a strong and loving family."

Marino reportedly IS in Chloe's life.  It's not clear how much time he spends with her, though.  Marino and Claire have six children:  Four sons and two adopted daughters.  Donna got married in 2009.
