The unlikely duo of Mick Fleetwood and Harry Styles haven't only conjured an unexpected friendship, but the two Fleetwood Mac and One Direction band members even write to each other regularly as penpals.

The drummer exposed the evolution of their relationship, explaining that he met the young British pop star while taking his kids to a One Direction concert. Last week, Styles took to the stage during a London show to present Fleetwood Mac member Stevie Nicks with a birthday cake, notes NME. The pop star was also caught having a blast and spinning around to the 1977 Rumours hit, "Go Your Own Way," at a Fleetwood Mac concert.

Fleetwood explained his friendship with Styles to The Mirror, stating "We're pen pals! 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 continued.

One Direction has recently undergone lineup changes with the loss of band member Zayn Malik but show no intentions of stopping. Their latest 2014 album, titled Four, eerily enough, foreshadows Malik's career-changing departure.

The band recently wrapped up their North American tour and is ready to lunge into their next bunch of dates in Europe. Fleetwood Mac will headline the Isle of Wight Festival in Glastonbury along with artists like Blur, The Prodigy and The Black Keys. Festival boss and live agent, John Giddings, claims money was the ultimate deciding factor in Fleetwood Mac's involvement.
