Jagged Little Pill was the third CD from singer and songwriter Alanis Morissette, released in 1995 and most likely the most listened CD for the rest of the decade. Everyone wondered who Alanis wrote the breakup song “You Oughta Know” about. Well, we can now say for sure who it was.

Yes, you've seen the implications in the 'pop-up' video and now former “Full House” star Dave Coulier told HuffPo Live that it was him! The line, “I hate to bug you in the middle of dinner” tipped him off. Coulier recently said, “We had already broken up…She called and I said, ‘Hey, you know, I’m right in the middle of dinner. Can I just call you right back?' When I heard the line, it was like, ‘Uh-oh.’”

So there you have it, it was Dave Coulier after all.

The Video May Not Be Suitable For Work.
