The news comes just days after three men - Anthony Rapp, Roberto Cavazos and Tony Montana - have come out blasting the award-winning actor.
Spacey's rep told Variety, 'Kevin Spacey is taking the time necessary to seek evaluation and treatment. No other information is available at this time.'
After Rapp claimed Spacey assaulted him when he was just 14, the actor apologized in a bizarre statement that was widely criticised.
In a Twitter post, the actor stated he did not remember the incident involving Rapp, but if he did, it was likely because he is gay and was intoxicated.
After the Twitter post, Montana Cavazos came forward accusing the star of sexual misconduct.
Talking to RadarOnline, Cavazos said: 'I went up to order a drink and Kevin came up to me and put his arm around me. He was telling me to come with him, to leave the bar. He put his hand on my crotch forcefully and grabbed my whole package.'
Following the scandal, Netflix and MRC decided to suspend production on House Of Cards season six, where Spacey had a leading role.
