(Cover) - EN Showbiz - Simon Cowell reportedly provided Britney Spears with "unheard of" lenience in order to secure her as a judge on his show.

The pop songstress recently joined the coveted judging panel of US TV talent show The X Factor alongside Demi Lovato and returning stars Simon and L.A. Reid.

During her first day on the job Thursday, Britney took a "break" as four contestants performed to three judges and an empty chair.

TMZ reports that Britney is afforded such allowances in her contract.

"[Britney secured] unheard of [deal terms]," a source told the website. "Simon is a smart and shrewd businessman who knew Britney could make his show and he was willing to give her just about anything to come on board -- and he did."

Britney is still the subject of a conservatorship order following her 2008 meltdown. It means her personal and professional decisions are overseen by her father and her fianc Jason Trawick, among others.

The songstress is reportedly getting paid in upwards of $15 million per season for her work on the show. (C) Cover Media
