Fans of X Factor judge Tulisa were left shocked by a foul-mouthed tweet from the singer.

The talent show star was in New York having a few casual drinks with friend and fellow pop star Rita Ora, when she posted a message on her official Twitter page saying: "N as 4 all u f****** hater...u can kiss my f****** ass #gettingpaid #bothered?"

Well it certainly seemed to bother quite a few of her fans as the 23-year-old reportedly lost more than a thousand followers as a result of the offensive tweet.

The N Dubz singer didn''t seem too phased though, later tweeting: "Always loose a few thousand followers when I av a drunken rant with a bit of harsh language..#wellworthit #f***em"
