LOS ANGELES — Former Hollywood hellraiser Charlie Sheen admitted he experienced some surreal moments at the premiere of his Netflix documentary "aka Charlie Sheen."

Sheen, 60, who celebrated eight years of sobriety on Sept. 3, was struck with wonder reuniting with his once-acrimonious ex-wife Denise Richards on the red carpet at Netflix's Tudum Theater. The "Wall Street" star was shocked again to see his one-time drug dealer chronicling the glam event with an iPhone.

"So I haven't been to a premiere in a couple of decades, a few things have changed," Sheen told the audience that included Richards, and former prostitution ring operator Heidi Fleiss. "I show up and my drug dealer has taken more photos than I have. And in the next minute I'm on the red carpet with my gorgeous ex-wife, like we're headed out on the town. What the hell happened?"

During his public Hollywood meltdown, Sheen was fired from the Chuck Lorre sitcom "Two and a Half Men" in 2011 after making about $1.8 million per episode.

The documentary subject admitted he was pleased the premiere only showed the first episode of the two-part Netflix series. The second will revisit his highly publicized substance abuse spiral in the late 2000s and early 2010s.
