When word spread that Alanis Morissette's bitter breakup anthem 'You Oughta Know' was about her former lover, 'Full House' actor Dave Coulier, we didn't want to believe it. John Stamos, maybe. But Uncle Joey Gladstone? With those cute cartoon voices and that spot-on 'Popeye' impersonation? The same Uncle Joey who played a quirky science professor (Mr. Egghead) to his best friend/college buddy's daughter's (little Stephanie Tanner) science class? Whose only dream was a little room in which to practice his stand-up routine that would one day eventually land him on the Star Search stage? No way. Morissette has stayed mum about the song's subject since its release in 1995. Coulier, however, is fessin' up.

The actor tells the Calgary Herald that he was driving when he first heard 'You Oughta Know.' "I said, 'Wow, this girl is angry.' And then I said, 'Oh man, I think it's Alanis,'" he said. "I listened to the song over and over again, and I said, 'I think I have really hurt this person.' I tried to contact her and I finally got a hold of her. And at the same time, the press was calling and saying, 'You want to comment on this song?' I called her and I said, 'Hi. Uh, what do you want me to say?' And she said, 'You can say whatever you want.' We saw each other and hung out for an entire day. And it was beautiful. It was one of those things where it was kind of like, 'We're good.'"

Now, if we could only get Warren Beatty all liquored up to talk a little Carly Simon.
