Who says grown men don't cry? We all know Rod Stewart is a huge soccer fan. He loves his Celtic team, and they won a big game against Barcelona. It was an emotional game for Rod, if fact, it brought him to tears.

Rod Stewart's been a huge fan of the Scottish soccer team (they call it Football in the U.K. and Europe) for a long, long time. He even mentions the Celtic in his song "You're in My Heart."

This is truly a touching video. It's a side of Rod that I don't think I've ever seen. Men...they do love their sports, don't they!

Here's a old video of Rod Steward working out with some players and talking about why he such a Celtic fan. By the way, the picture at the top? Yes, Rod is wearing a Celtic warm-up suit.
