Celebrities are incensed over Kevin Spacey's "sincerest apology" to Star Trek: Discovery actor Anthony Rapp.

Rapp told BuzzFeed that when he was 14, the House of Cards star, inebriated at a party thrown at Spacey's apartment, made a sexual advance on the then-underage actor. Rapp said Spacey placed him on a bed and climbed on top of him but Rapp was able to leave before the encounter could go further. 

Kevin Spacey, at the Oscars in 2014, has been accused by Anthony Rapp of making a sexual advance when Rapp was 14.

In a statement on Twitter, Spacey also came out about his sexuality, explaining "I choose now to live as a gay man."

While House of Cards creator Beau Willimon called Rapp’s story “deeply troubling,” he said he was never aware of any misconduct by Spacey during their time working together on the Netflix political drama. (Willimon left the show after Season 4.) 

“I neither witnessed nor was aware of any inappropriate behavior on set or off,” he told USA TODAY in a statement provided by his representative Rachel Aberly. That said, I take reports of such behavior seriously and this is no exception. I feel for Mr. Rapp and I support his courage.”

Rose McGowan, who is one of dozens accusing Harvey Weinstein of sexual misconduct, urged the media to BE THE VICTIM'S VOICE" and maintain a focus on Rapp. "Help us level the playing field," she tweeted.

She later added, "Bye bye, Spacey goodbye, it’s your turn to cry, that’s why we’ve gotta say goodbye."

Wanda Sykes chastised Spacey for what she says was an attempt to "hide under the rainbow."

American Idol Season 2 runner-up Clay Aiken, who came out as gay himself in 2008, told Spacey, “You can choose to act like a pervert; you can't ‘choose’ to be gay." 

Larry Wilmore deemed Spacey's statement "wrong on so many levels."

Billy Eichner tweeted, "Kevin Spacey has just invented something that has never existed before: a bad time to come out."

Singer Richard Marx called the allegation "disgusting. Period."

Actress Louise Brealey believes "Spacey trying to hide behind coming out & offering drunkenness as an excuse for jumping on a child shows his breathtaking arrogance."

Comedian Paul F. Tompkins said, "Thus with one statement 'Carson impression at the 2017 Tonys' moves down to 3rd on the list of the worst things Kevin Spacey has ever done."

Full Frontal with Samantha Bee writer Travon Free reminded his Twitter followers "Being gay is not an excuse for trying to molest children."

Actress Aisling Bea tweeted that she believes there are others who have "a Kevin Spacey story" of their own.
