Aly & AJ do not hold back in the new, grown-up version of their throwback hit.

On Tuesday (December 29), the pop sister duo released the long-awaited, explicit recording of their fan-favorite track, “Potential Breakup Song.

In the new explicit version of the song, the sisters go fully off, dropping the F-bomb several times and adding a few other amped-up jabs fans have been waiting years to hear and passionately sing along to.

The updated version follows the song's popularity on TikTok this year. Everyone from Gordon Ramsay to the Baltimore Orioles players got in on the resurgence of the catchy, mid-2000s bop by lip-syncing to it in their videos.

Listen to the updated "Potential Breakup Song," below:

"Potential Breakup Song" was released in 2007 on the sisters' third album, Insomniatic. It peaked at No. 17 on the Billboard Hot 100 and has since skyrocketed to 60 million streams and counting on Spotify.

The 2020 revival of the angsty track makes total sense to the former Disney starlets.

"It was a year where a lot of people didn't feel safe and listening to old music or watching an old movie was a comfort," AJ said to EW. "And it was one of those things where it's like, yeah, 'Potential Breakup Song' — let's break up with Trump."
