Demi Lovato and Alanis Morissette "Oughta Know" at American Music Awards

by at .

WARNING to all men around America: do not mess with Demi Lovato.

Or Alanis Morissette, for that matter. But we already knew that.

Billed by ABC ahead of time as an “epic” duet, the singers came together on stage at the 2015 American Music Awards and took us back in time to 1995.

In celebration of Morissette released her iconic album, “Jagged Little Pill,” the Canadian star teamed up with Lovato for a rendition of “You Oughta Know.”

The performance of this anger-filled breakup anthem actually marked Morissette's first-ever time performing at the American Music Awards, despite having won two of its trophies back in the day, Favorite Pop/Rock Female and Favorite Pop/Rock Album in 1997.

In August, meanwhile, Morissette also performed “You Oughta Know” with Taylor Swift as part of the latter’s 1989 tour.

Moreover, she stopped by The Late Late Show with James Corden to update Ironic in hilarious fashion just a couple weeks ago.

Isn't it nice to have Alanis back in our lives?!?

Which version do you like better? That of Alanis and Taylor or that of Alanis and Demi?

(Note to Wilmer Valderrama:  We're not kidding, dude. After viewing this footage, you are going to want to stay loyal to Lovato. She means business.

Hot, vengeful, vindictive business. Don't cheat, man.)

I'm very uncoordinated. I'm surprised I don't fall onstage more.
