The official numbers are in.

Beyonce and Adele are both likely performing at February's Grammys, according to a producer of the event.

See Beyonce, Katy Perry, Snoop Dogg and Mariah Carey dressed in their Santa Claus best.

The 'Teenage Dream' superstar just crossed 90 million followers on Twitter, but half of them aren't actually real! Yay!

Happy 4th of July! Celebrate the stars and bars with all-American jams from Katy Perry, Demi Lovato, Taylor Swift and more.
