Lady Gaga performed at the iHeartRadio Music Festival at the MGM Grand in Las Vegas Saturday night, and took a moment to put a serious spin on the superstar fest.

Gaga dedicated her performance of "Hair" to Jamey Rodemeyer, a 14-year-old fan who committed suicide last week. Rodemeyer Tweeted Gaga thanks for her positive inspiration before he killed himself. Said Gaga at the fest:

    "We lost a little monster this week, and I wanted to dedicate this song to him tonight because he was really young. ... I know it's a bit of a downer, but sometimes the right thing is more important than the music, isn't it? Let's do this one for Jamey."


Gaga has vowed to meet with President Obama over Jamey's suicide; she says it is one too many that has come as the result of bullying. Mother Monster wants to make bullying a hate crime.
