Lady Gaga

Gojira, Alice Cooper, Machine Head, Mammoth, Pantera, Ghost and more all paid tribute to Ozzy Osbourne onstage after the musician's death on Tuesday.

Lady Gaga said that Nine Inch Nails and Radiohead were big inspirations for her new album 'Mayhem,' as well as David Bowie and Prince.

The pop star revealed to Brian Johnson that she was once an extra in one of AC/DC's videos.

These acts truly shook things up when they took the stage!

Sounds like a cool collaboration.

He has solid reasoning.

The singer shares a complimentary view of the pop star.

Now that would've been a sick collaboration.

Demons, gravestones, blood and motorcycles on an album cover often mean you're about to hear some metal. But not always.

James Hetfield had to overcome mic issues during Metallica's collaboration tonight with Lady Gaga at the Grammys.

Kristi Capel, a newscaster at WJW-TV Fox 8 in Cleveland, is probably going to want this one back. On Monday while talking about Lady Gaga's performance at The Oscars, where she sang a musical medley tribute to "The Sound of Music," it seemed like Capel was trying to pay Lady Gaga a compliment. But she failed miserably.

Did we miss something at Fashion Week? Is barf the hot thing this season, because we thought it was going to be brocade? Now Lady Gaga AND Justin Bieber have barfed onstage in the past week. We will give Gaga props for not letting it stop her. Because that is seriously a lot of ralph.
