Our favorite, however, is when where she challenged Sarah Geronimo to a booty-shaking contest to the tune of "Anaconda" and "Fancy," which the Pop Princess gamely accepted. Want to know what happened? Here's a GIF-filled recap!
Alex didn't waste time showcasing her twerking skills and immediately went at it.
So Sarah countered with her tight leather outfit and mighty impressive rapping skills.
Alex literally stole her frenemy's spotlight by shaking it sideways.
But Sarah isn't one to stay on the sidelines, so she shook her buns like no one's watching.
Oh no, she didn't! Alex knew she had to come up with something big.
And so she did. Behold, ladies and gentlemen, the money shot! How are your anacondas holding up?
Alex threw all her inhibitions out the window and just gave it all. Her opponent is obviously not pleased.
Afraid that she might lose, the Pop Princess retaliated by flaunting her backside in a "highly captivating" manner. And guess what, it worked!
Alex, however, flaunted more than just her buns. We don't know what she just did, but we'd like her to do it over and over again.
Sarah and Alex ended their showdown by giving each other a slap in the butt. We should totally watch Sunday variety shows more often.
