WATCH: Anne Hathaway leaves Kelly Clarkson on the floor with 'Since U Been Gone' cover

In case you forgot, Anne Hathaway has amazing singing chops.

While appearing on The Kelly Clarkson Show, the actress left Clarkson on the floor as she belted out the chorus to the host's hit song Since U Been Gone.

Hathaway and Clarkson were playing a game of "Sing That Name That Tune" where they had to guess a song by its instrumental then sing it after. The WeCrashed star was beating Clarkson at the game, guessing and singing every tune—from Billy Joel's Piano Man to 90s bop MMMBop.

The highlight of the segment, however, was when the track for Since U Been Gone started playing and Hathaway effortlessly sang at the breakup anthem at the top of her lungs.

Clarkson fell on the floor in defeat, saying "How did you know it from just that?"

"Kelly, if you do not understand how much we all love that song, everybody knew it from the first line," the actress answered.

Clarkson then joked about calling it a day as she couldn't even guess her own song.

"Should I just quit?" the host said. "This is embarrassing... Whatever, I'm so happy for you. Jesus, take the wheel."

Clarkson released Since U Been Gone in 2004 as part of her Breakaway album. The song peaked at No. 2 on the Billboard Hit 100 and sold a million copies in the US.

Fans of Hathaway might be familiar with her singing capabilities. She famously starred as Fantine in the 2012 movie musical Les Miserables—which she won an Academy Award for.
