The former American Idol judge was romantically involved with gun manufacturer Colton Melby from 2003-2004 — who was still married at the time to his wife, Maryann.

Sources close to the situation told Star at the time, "Maryann is heartbroken. She still loves Colt. Even though he moved out in December 2001, she hoped he'd come back. Maryann never saw this coming. When Colt moved out, she asked him, 'Is this the end?' Colt told her, 'Don't file for divorce.'”

The insider continued, "Out of the blue, Colt filed for divorce 18 months later. Then Maryann hears about articles saying Paula's been dating 'divorced' businessman Colton Melby since late March. She's distraught. Not only is Colt seeing another woman, he's callously living a lie, because he's still married."

As Paula's song goes, opposites attract.
