Oops, he did it again.

Simon Cowell is going to fire pop phenomenon Britney Spears as one of his regular judges on his singing reality series “The X Factor,” or so Us Weekly is reporting.

The “Hold It Against Me” singer may not be joining the show for another run, sources revealed after the show wrapped up its second season on Dec. 20.

Spears had stated in earlier interviews that she would be coming back to the talent show for another gig, but that doesn’t seem to be the case now that the Fox hit has finished filming.

"Britney will get the boot," Us quoted an "insider" saying about Spears, who joined the show in May, along with younger newcomer Demi Lovato. "Producers wanted her for the long haul, but it isn't working."

One of the reasons could have to do with the pop star’s astronomically high salary. Spears raked in $15 million for her stint on the show, and many believe that the low-energy mentor has not earned her salary.

“They paid all that for her to say 'amazing' and offer half-claps," an insider told Us.

Another source revealed why the co-creator of the reality singing series, Cowell, is ready to kick Spears off his show:

“He wanted crazy Britney, but he got boring Britney."

Spears shouldn’t take her forced departure to heart, however. She joins a list of celebrities who were given the axe by the famously mean music mogul.

Even though the series has only been around for two seasons, Cowell already has fired celebrities like Paula Abdul, Nicole Scherzinger and Cheryl Cole.

Most recently, judge L.A. Reid announced his decision to quit in early December.

Even though the end of Spears’ run appears imminent, Cowell hasn’t always had it out for her.

During a conference in October Cowell, 53, said about the “Oops! I Did It Again” star:

"[She’s] a lot better than everybody thought...She's very engaged...She has been, I think, a very, very good judge."

But Spears' professional relationship with Cowell isn’t the only thing that seems to have fizzled.

She and fiancé Jason Trawick have been butting heads.

"They are pulling away from each other," a pal explained to Us Weekly. "Unless things change, they will split for good."
