Spears is nominated for Best Female and Best Pop Video categories, for her track Piece of Me.
But Williams has told Spears not to be concerned if fans fail to acknowledge her achievements at the ceremony - insisting she has already made a hugely successful dent in the music industry.
He tells People.com, "She's made her mark with her career. She's super-talented. She's an entertainer."
