Mick Fleetwood of Fleetwood Mac says that he's "penpals with Harry Styles," the fronter of One Direction.

Speaking with the Mirror, Fleetwood explained, "We're penpals! I took my two 13-year-old daughters and their mates to see One Direction."

"And that point, the girls are going, 'Dad, just don't embarrass us! No dad dancing!'

We had the meet-and-greet thing and what happened in front of my daughters was Dad became a superstar!"

"One Direction all wanted to meet me! My ante got upped. All their songwriting team wanted to meet me.

That's when I met Harry and he's come to three of our shows. He writes to me from weird places."

Fleetwood top the bill at the Isle of Wight Festival later this month.
