Singer Ricky Martin has joined Lady Gaga in honoring the memory Jamey Rodemeyer.

Rodemeyer is the 14-year-old Buffalo-area teen bullied to death for coming out gay. More than 500 people showed up to pay their respects to Rodemeyer at his at funeral held over the weekend. The Williamsville North High School freshman was found dead outside his home last Sunday.

In a YouTube video posted in May, Rodemeyer said Lady Gaga had inspired him. “Lady Gaga, she makes me so happy, and she lets me know that I was born this way. And that's my advice to you from her. People are born this way. All you have to do is hold your head up and you'll go far,” he said in the clip. “Just love yourself and you're set … It gets better.”

Martin, who came out gay in his 2010 memoir Me, changed his Twitter profile picture to an image of Rodemeyer in that YouTube clip.

“THIS NEEDS TO STOP NOW,” Martin tweeted to his nearly 4 million followers. “HOW MANY LIVES LOST BEFORE SOMEONE LISTENS.”

During a Saturday performance in Las Vegas, Lady Gaga paid tribute to Rodemeyer.

“Bullying is for losers,” she told the audience.
