The man who was staying at Boyzone singer Stephen Gately's (pictured) house on the night that he died claims he'd been having an affair with Gately and his partner for more than two years, despite reports the three had just met the previous evening.

Georgi Dochev tells a Bulgarian radio station he had been having a long-term sexual relationship with Gately and his partner, Andy Cowles, before the singer's sudden death in October.

"We met more than two years before that night," Dochev, who is a student, told the radio station, saying the three of them regularly met for dates and sex. "Well, we didn't go fishing or go to the library. I did it with both of them."

Dochev claims the three had sex on the couch the night Gately passed away and that the pop star was extremely drunk when he fell asleep. He claims he and Cowles had sex with each other again in the morning before discovering Gately's body.
