Jared Leto Apologizes to Taylor Swift ... I Think You're Awesome

Jared Leto says he's sorry for going off on Taylor Swift.

TMZ broke the story ... Jared was in the studio with his Thirty Seconds to Mars bandmates when he flipped from admiring T-Swift's 16 count, to saying "F*** her!"

Jared tweeted an apology to Taylor and her fans, saying, "The truth is I think Taylor Swift is amazing + an incredible example of what's possible," adding, "If I hurt her or her fans my sincerest apologies."

TMZ posted video of Jared in a studio session where he and a bandmate were using Taylor's songs as inspiration and in a moment of frustration hurled the f word. It's actually a compliment, if you break it down.
