It wasn’t easy being Brad Pitt in the 1990s!

The Academy Award nominee opens up in a new interview with The Hollywood Reporter, revealing that he suffered from depression after his rise to fame in the 1990s and turned to Mary Jane for support – and RadarOnline.com has the details.

“I got really sick of myself at the end of the 1990s,” he admits. “I was hiding out from the celebrity thing; I was smoking way too much dope; I was sitting on the couch and just turning into a doughnut; and I really got irritated with myself. I got to: ‘What’s the point? I know better than this.’”

Miley Cyrus is firing back at fans who have threatened her good friend, Kelly Osbourne after the controversial birthday cake she presented to Miley spawned rumors of illegal drug use.

The former Disney star was filmed at her 19th birthday party on November 22 saying: “You know you’re a stoner when your friends make you a Bob Marley cake -- you know you smoke way too much f***in’ weed."

As RadarOnline.com previously reported, after Miley’s risqué comment, Kelly jumped straight in, quipping: “I thought salvia was your problem, Miley."

Miley Cyrus was late for the birthday party Kelly Osbourne threw for her Tuesday night, but she made up for it with what she told the crowd.

The birthday cake she was presented was decorated with the face of the late Bob Marley, the legendary reggae artist.

In video of the party obtained by The Daily, Miley very clearly says, “You know you’re a stoner when friends make you a Bob Marley cake — you know you smoke way too much f***in’ weed."

Her friend Kelly then jumped in saying, “I thought salvia was your problem, Miley."

That was a reference to Miley's videotaped incident, where she smoked salvia from a bong, something she later called a "bad decision".

Miley's party was thrown at Beacher's Madhouse Club at the Roosevelt Hotel in Hollywood. Her parents, boyfriend Liam Hemsworth and pal Rumer Willis were all there to celebrate her19th birthday.
