In a recent interview with Charlie Rose, Tiger Woods revealed the one regret he has in life — and it's not what anyone would have thought.

As fans know, the pro golfer was accused of having multiple affairs in 2009, and eventually admitted to cheating on wife Elin Nordegren, which led to their 2010 divorce.

Even Charlie was taken aback by his answer, asking, "That's the only regret?… Of all the things that's happened to you?"

Tiger responded, "That's the only regret… All the things I've been through are tough, yes. They've been tough, but they've been great for me, but I wish I would've gone one more year at Stanford."
