Back in 1989, Blake Lively's half-sister Robyn Lively starred in "Teen Witch," a movie that has one of the best (and most awkward) rap scenes ever.

The movie went on to become a bit of a cult classic, thanks in large part to Mandy Ingber's incredibly embarrassing/awesome delivery of the song "Top That."

And now, 24 years later, she's re-dong it for Glamour magazine.

Check out the hilarious video above. For those of you who haven't seen the movie, Ingner's Polly tries to impress her too-cool-for-school crush by challenging him to a rap battle.

Here's the original below:

Ingber went on to add "The Relic" and "Exit to Eden" to her acting resume before becoming a celebrity yoga instructor, with clients like Jennifer Aniston.
