"You can do side bends or sit-ups, but please don't lose that butt."

Sir Mix-A-Lot reminded the big booty women of the '90s what Queen told them years before: "Fat bottomed girls, they make the rockin' world go 'round."

But he said it as only Sir Mix-A-Lot could.

So who was the diva of derrieres that served as the rapper's posterior muse? Jennifer Lopez, he told TMZ, was the voice he wanted to hear when he picked up 1-900-MIXALOT.

There is some curvaceous controversy around this revelation. Seattle Metropolitan doesn't think the O.G. of big B has his timeline correct:

"Lopez didn't join In Living Color until Sept. 1991. Mack Daddy, the album on which 'Baby Got Back' appeared, was released on Feb. 4, 1992. So if we're to believe Mix, he saw J-Lo shaking it, shaking it, shaking that healthy butt on TV in September and then managed to write the greatest ode to derrieres of all time, record it, mix it, and add it to an album that still had to be pressed, distributed and marketed - all within five months? It's ... dubious."

Well, His Royal Booty Master did say that when they "toss it and leave it" he pulls "up quick to retrieve it." Was five months enough time?

At any rate, the song has lasted decades and crossed generations as a song with sort of a silly reputation, but Sir Mix-A-Lot says it wasn't intended to be a goof. He told Seattle Pi in a 2013 interview:

"You know, when I talk about 'Baby Got Back' - 'Baby Got Back' was actually a serious song, but I realized that I didn't wanna come off as, you know, as preachy. So what I did was I kind of kept it tongue-in-cheek but if you listen close enough to the song, it was a slap in the face of the establishment that was trying to define what all women should look like at that time. They wanted all women to look like heroin addicts. It wasn't the case. And when I did that song, you had half of the women that were offended and the other half saying, 'Thank God, about time.'"

For now, we have to go with Sir Mix-A-Lot's version of events that Lady Lo has the back of all backs and she isn't giving up the crown anytime soon.
