Hip hop mogul Pharrell Williams has advised Britney Spears not to worry if she fails to win a gong at this year's MTV VMA awards - because she is too big a star to bother about grabbing any further honors.

The superproducer, who worked with the Toxic hitmaker on hit tracks I'm A Slave 4 U and Boys, is backing the singer to walk away with a handful of awards at the ceremony on September 7th.

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."

"I'm not sure (if she will win). I don't even know if it really matters whether she wins or not."
