(Cover) - EN Showbiz - Esperanza Spalding has become the victim of a web attack launched by angry Justin Bieber fans.

The little-known jazz bassist and singer, 26, took home the Best New Artist award last night at the Grammy Awards despite 16-year-old Justin being favourite to scoop the gong at the prestigious music ceremony.

Following the jazz artists surprise win, false statements and taunts have been added to her Wikipedia page by frustrated fans of the pop sensation.

After a sentence noting her triumph, for example, a user added the statement; Justin Bieber deserved it go die in a hole. Who the heck are you anyway?

Other comments - which were posted before being quickly removed included the singers middle name being changed to Justin and Quesadilla.

Esperanzas Grammy win was written up with the addition, Even though no one has ever heard of her! Yay! At the end of her biography one hacker wrote Biber 4 Lyfe.

Justins unexpected loss at the music event left him disappointed. But unlike the Wikipedia user fans, showed no bitterness backstage at the event. He also asked his fans to remain calm after he missed out on the prize.

I had no clue what was going to happen; I worked really hard these past few years and you know, Im not going to lie I was disappointed, he told MTV News after the winner had been announced. Im inspired to work harder than I did last year. Bieber fans, dont get too upset. (C) Cover Media
