I fucking hate Kelly Clarkson...

"She knew it from the boom-boom-boom-boom!"... Why didn't you, Kelly? IT'S YOUR SONG! 😂

Anne didn't just sing Kelly's song, she knocked it right out of the park!

"Dont believe Anne when she says she cant sing" - she literally has an oscar for a musical 😂

Kelly: I love competition!!
Anne: I invented competition...

that bit with kellys song will never not be funny

That Pressure/Ice mashup was banging

annie singing whilst kelly raps in a pressure/ice mashup is not on any of our bingo cards oml

4:29 I cracked up when Kelly fell to the floor! 😂

She missed her own song! 😱

Anne woke up and chose violence

She had her chance. She blew it.

I saw this clip before but this time i noticed that anne was actually singing slower than expected and the band immediately corrected the tempo for her. real pros

I love how Kelly didn't know the chorus to MMMBop but could do the whole Ice Ice Baby rap XD

Anne not only owned Since You've Been Gone she aggressively stepped forward and owned the stage.

Fun fact: Kelly actually sang a song for an Anne Hathaway movie (Breakaway for Princess Diaries 2)

"SHE KNEW IT FROM BOOP-BOOP-BOOP-BOOP-BOOP!" 😂

I would 1000% pay for that mashup in full!!!!!

The way Kelly drops at the reveal, it was like Anne sniped her with the first word.

ANN HATHAWAY CAN DEFINITELY SING!!!!!

She is soo real for saying "you do not understand how much we all love that song! Everybody here knew it!" 😂
