Prince helped a fan break up with his cheating girlfriend on TV while shooting an agony uncle skit during a recent appearance on pal Arsenio Hall's late-night show.

The fan, Steven, explained that his girl was seeing an ex in Oregon while he was trying to make a life for himself in Los Angeles, and asked the Purple Rain singer for advice.

The superstar went one better and agreed to call the woman, called Keegan, and break-up with her himself.

Inspired by the lyrics from his own When Doves Cry hit, Prince said, "In this relationship, things are much harder than in the real world. Keegan, in this life, you're on your own. Keegan, this is what is sounds like when Steven breaks up with you."

The speechless ex finally responded, "I wanna be sad, but also if you're breaking up with me, I can't be that sad."

Keegan then cheekily asked Prince, "Also, are you perhaps available?"

The pop star chuckled and replied, "No, I'm not available."
