Britney Spears is facing some serious allegations regarding her time on The X Factor.
Louis Walsh, a judge on the U.K. version of the hit singing competition series, claimed in a new interview that the American pop star was heavily medicated when they worked together back in 2012.
At the time, the "Stronger" singer was a full-time judge on the reality series while the The X Factor U.K. star was simply filling in for a bronchitis-stricken Simon Cowell during auditions in Kansas City, Mo.
"I was sitting with Britney for two days, and after every few auditions, she would go…" Walsh told the Irish Independent on Sunday, June 13, before imitating Spears allegedly slumping over at the judges' table. "They would literally have to stop the show and take her out because she was on so much medication and other stuff.
"I felt sorry for her," the Irish music manager added. "Here she was, the biggest pop star on the planet, and she was just sitting there physically, but she wasn't there mentally. She had a lot of problems."
In May 2012, Spears was hired to replace Nicole Scherzinger as a judge for the second season of the U.S. version of The X Factor, joining Cowell, L.A. Reid and fellow new judge Demi Lovato, who replaced Paula Abdul. With a reported salary of $15 million, she became the highest-paid judge on a singing competition series in television history.

"She was getting millions of dollars to do it, so why the f**k wouldn’t she sit there?" the 68-year-old responded when asked if he thought Spears should have been receiving help rather than starring on a TV show.
Spears has admitted in the past that her time on The X Factor wasn't easy for her. In an interview with Elle, she said that as a mother of two young boys, she struggled with critiquing contestants.
"I was having panic attack after panic attack," she told the outlet in 2012. "I got over that quickly, though, and realized that I was helping them by being honest. … Personally, I think that’s the toughest part about being a judge on The X Factor. Most of them are still developing, and it's hard to tell such young kids whether they have what it takes or not, so I try to be as protective as I can with their hopes and dreams."
Spears did not return for the show's third and final season, which ended in December 2013.
