Tulisa Contostavlos has reportedly quit The X Factor after a row with producers.
The N-Dubz star, who joined the judging panel in 2011, has apparently been planning to leave since learning that Nicole Scherzinger has already been invited back for the next series.
"Tulisa had a blazing row with producers when she found out Nicole was coming back," a source told the Daily Star Sunday.
"She can't stand working with her and Tulisa is not enjoying the job at all.
"The producers couldn't wait to get rid of her. She turned her dressing room into a nightclub and would boom out loud music.
"Despite leading Little Mix to victory [in 2011], she wasn't as available to her acts off-stage as people think.
"Tulisa got the hump when she was warned about her behaviour."
Contostavlos's dad recently revealed that his daughter wants to leave The X Factor as she "only does it for the money".
Sharon Osbourne has reportedly already met with producers about a potential return to the show later in the year.
