Dan Marino fathered a child with a former CBS Sports production assistant and subsequently paid her millions to keep it quiet.

The daughter was born in 2005.

“They had an affair, and she had a baby,” said a source. “Everything was on the down-low and secretive.”

Marino admitted to the affair on Wednesday.

“This is a personal and private matter. I take full responsibility both personally and financially for my actions now as I did then,” he told The Post in a written statement. “We mutually agreed to keep our arrangement private to protect all parties involved.”
