Lady Gaga has always been an advocate for the underdog -- her "little monsters" - and now she's taking the fight to the White House.

14-year-old Jamey Rodemeyer became the latest teen to commit suicide over bullying on Sunday (he was gay.) Back in May, he had cited Gaga as an inspiration to keep going in a video he posted online. "She lets me know that I was born this way," he said. "And that's my advice to you from her: You were born this way. All you have to do is hold your head up and you'll go far."

On Wednesday, Gaga Tweeted about his death. "The past days I've spent reflecting, crying, and yelling. I have so much anger." She said that bullying "must become illegal. It is a hate crime." She continued:

"I will not stop fighting. This must end. Our generation has the power to end it. Trend it #MakeALawForJamey."

Today's full interview with Brad Pitt is out, and the actor is defending himself over his recent, controversial interview with Parade magazine.

In the interview, Pitt spoke negatively about his marriage to Jennifer Aniston. But he tells Matt Lauer that the quotes were "misconstrued" ... though he admits to not even having read the interview.

"I don't read these things. By choice. ... I know my intentions, and I know what I believe, and I know things get misconstrued. I live outside of that and it's a much healthier place to be. ... I don't want to live on guard."

Pitt told Lauer that Jen has not contacted him about the media storm, and defended her. "She's a valuable person," he said. "We spent seven years together. ... She's good people. There should be a statute of limitations on this thing."

Adorbs!
