"@britneyspears be nice to @SimonCowell tonight on #xfactor," Will.i.am tweeted on Wednesday evening. "Underneath that armour he's a softy… wishing you #willpower.. #itsbritneyb***h.

"@iamwill Oh stop you know I"m not the one that needs a "be nice" reminder even though @SimonCowell is calling me the 'Queen Of Mean" ; LOL," Britney then replied, following Simon's recent comments that Britney was even meaner than him on the show.

Will.i.am then added: "@britneyspears I meant be nice to @SimonCowell cuz your the queen of pop & you & I gotta new MEAN killer song coming… congrats on #xfactor."
