Jessie J has apologized to fans after Internet pranksters hacked into her official website and posted a crude message about Lady Gaga.

The British singer was left fuming when her website was illegally accessed on Saturday, with pranksters posting a rude note about her record label and the pop superstar in the news section. The message, which has since been removed, read: "The whole Universal Republic (Universal Music) can suck Lady Gaga's d**k."
