X Factor favourite, Marcus Collins was left stunned after receiving a blow of abuses and racist remarks from an unknown person over a phone in the middle of the night.

Collins, a mixed race gay singer, received the call at 2:30 a.m. on Tuesday, and he initially thought it was a friend who called to know if he was still out, until the caller spoke, reports The Sun.

"The voice on the other end of the line was just full of hate and spewed all sorts of racist and anti-gay abuse. He was saying, 'You don't deserve to be on the show. Who do you think you are?' and calling him every name under the sun. Marcus couldn't believe his ears and he couldn't understand how anyone got hold of his number in the first place," source said.

According to the newspaper, the Scouse singer told the production team, and the production chief asked if he wanted to report the matter to police, however, Collins refused to go to police, but said he believes the caller was a casual acquaintance from his home town Liverpool.

"He has an idea of who it might have been and is going to try to find out if his hunch is correct. Fortunately for him, he's no shrinking violet so can take it," the source added.

Collins is the only male singer left in the contest and is one of the favourites to win.
