“You know, it's brave of him,” Abdul, 53, explained to ET. “I don't have anything bad to say about Charlie. I love him. I'm happy that he's taking it upon himself to do the best thing and raise awareness, and, you know, I wish him nothing but the best.”

The former Two and a Half Men star shared the news about his HIV diagnosis in an interview with Matt Lauer on Today, and revealed he felt relieved.

"I think I released myself from this prison today," he said of secret he kept for nearly four years.

Sheen’s manager, Mark Burg, is meeting with publishers to discuss the possibility of him writing a book about his career and health journey.

Natalie Kenly, who lived with the star in 2011 when he got the virus, says she is standing by him as well.

"I knew Charlie as the man, and not the myth or the legend," she told ET. "Charlie didn't pay me to keep quiet about his HIV diagnosis or anything else. I was tested. I've been tested several times since then, and I also don't believe I was around when he was diagnosed or contracted the virus."
