Ricky Martin, Ellen DeGeneres and Jason Collins were among the out celebrities mourning the loss of comic great Robin Williams.

The Oscar-winning actor's body was found just before noon at his home in California. According to a spokeswoman, Williams had been “battling severe depression of late.”

Among his many memorable roles, Williams, 63, played a gay man opposite Nathan Lane in the 1996 film The Birdcage. In the 2014 film The Boulevard, which premiered at the Tribeca Film Festival but has yet to find a mainstream distributor, Williams played Nolan Mack, a gay man coming to terms with his sexuality.

Ellen DeGeneres said in a tweet to followers that she was “heartbroken.”

“I can't believe the news about Robin Williams,” she messaged. “He gave so much to so many people. I'm heartbroken.”

“I am stunned and just reeling from the news of Robin Williams' death,” wrote Neil Patrick Harris. “He brought so much joy and heart to millions... Just, wow.”

“Shocked and saddened,” Ricky Martin said.

“RIP, great soul,” added George Takei. “We hope your spirit has found peace.”

Jason Collins sent prayers to “his family and loved ones.”

“So sad to hear the passing of @RobinWilliams. One of the best ever,” he tweeted.
