Elton John Welcomes Charlie Sheen to AIDS Charity Bash

Charlie Sheen attended the 24th Annual Elton John AIDS Foundation's Oscar Viewing Party at The City of West Hollywood Park last night in West Hollywood to support the fight against AIDS. Among the other luminaries in attendance were Beck, Steven Tyler, Heidi Klum, Mariah Carey and "Transparent" star Jeffrey Tambor, as well as Kelly Osbourne and Caitlyn Jenner.

While many stars watched the entire ceremony under Elton’s tent, Charlie arrived fashionably late — if you consider after the telecast ended to be “fashionably late.” Still, Charlie was in high spirits, arriving wearing a custom T-shirt emblazoned with his own face and the message “Stay positively negative.”

Charlie arrived with two male friends and a blonde woman. When questioned about his fashion choices, Charlie said, "If somebody said, 'You're not wearing a tie.' Well, I'm at an AIDS event and I brought my HIV." Charlie, of course, came clean about his HIV status in November after The National ENQUIRER exclusively broke the story.

The former “Two and a Half Men” star, 50, caught up with hosts Elton, 68, and husband David Furnish, 53, to take some jolly photos before going on to pose with fans. Charlie also took time to chat up music heavyweight Russell Simmons.

Elton later posted a photo on social media alongside Charlie and David, writing: “Glad to see Charlie Sheen at the party. In great form and in great spirits. @charliesheen @ejaf @davidfurnish #EJAFOSCARS #OSCARS.”

This year’s bash featured a dinner by celebrity chef Gordon Ramsay! Elton’s annual event has raised more than $50 million for his AIDS foundation.
