Paula Abdul, that crazy-cool, straight-up phenom, turns 53 today. Did you know she gave Janet Jackson her first moves? And did you know she also outperformed Janet at the 1990 American Music Awards? It's all true. And amazing to watch.

Here's Paula performing "The Way That You Love Me" at the '90 AMAs. Janet follows up with "Escapade." They're both great, but Paula's got that old-school showbiz firepower.

And if you wanted to see Paula formally  school Janet, watch as she teaches her moves in this rare clip. Happy birthday to the vibeological empress!
