After winning two awards at the MTV Music awards, Justin Bieber spent the wee hours of the morning in a gay club.

The 'Baby' singer forgot about claims made by Mariah Yeater that he is the father of her four-month-old son by hitting the Kremlin nightspot in Belfast, Northern Ireland, after winning the Best Pop and Best Male accolades at the event.

"Justin managed to shake off the thousands of fans who were following him around the city," the Sun quoted a source as saying.

"He went to the official MTV party at the Europa hotel with his girlfriend Selena Gomez before being smuggled out in secret," the source added.
