katy singing Katy Perry covers Rebecca Black's 'Friday'We prefer Nick Jonas’ version, but Katy Perry’s isn’t half bad.

Perry decided to have a little fun at her concert in Melbourne, Australia, on — what else? — Friday, Apr. 29. The “Teenage Dream” singer put her own spin on Rebecca Black’s infamous hit song “Friday.”

“So I can’t play the flute, but it doesn’t really matter,” Perry tells the crowd. “You know why? ‘Cause all magical things happen on a Friday.” With that, she launches into her cover of “Friday,” which prompts the crowd at the Rod Laver Arena to cheer.

The concert-goers clearly enjoyed the surprise — cheering and singing along to the chorus. An added bonus is that they finally learned Sunday comes after Saturday, which comes after Friday… or not because Perry only performed half of the song.
