Kevin Spacey's brother urged the star to "admit his guilt" over fears he will commit suicide over the sexual assault allegations made against him.

The Oscar-winnning actor, 59, has been accused of sexual misconduct by a number of people following claims made by actor Anthony Rapp in 2017, accusing Spacey of assaulting him when he was 14 years old.

The allegations cost Spacey his job on Netflix drama House of Cards, and he is set to appear in court in March (19) after being accused of groping an 18-year-old in 2016.

Spacey's brother Randy Fowler, 63, told British newspaper The Sun that he is worried about the disgraced star, and urged his brother to “take his punishment”.

"I’m worried about him committing suicide. But then you have to think, ‘Nah he’s too narcissistic, he probably wouldn’t do that’," he explained. “But you’d be surprised what people will do when they’re faced with the truth and they can’t deal with it. All your money isn’t going to cure your damaged soul.”

Fowler, who has been estranged from Spacey for more than a decade, also claimed that the allegations made against the Baby Driver star were not even “one per cent” of the true extent of his predatory behaviour.

"How many hundreds of people are out there that haven’t said a word that don’t have the courage to come forward? You think 30 is even one per cent?” he fumed.

Fowler also criticised Spacey's management for allowing him to release the bizarre video in December (18), in which he denied the sexual assault charges against him while in character as his former House of Cards character, U.S. President Frank Underwood.

“I don’t understand the people that are representing him, why they don’t stop this type of nonsense," he sighed.
