"She's a friend, but people are going to say what they want about it," Doherty told the magazine at the MTV European Music Awards in Munich. "She's happy now, and so am I."
After several brushes with the law and trips to rehab, the Babyshambles frontman said he is clean and sober.
"It's nice to be able to remember a gig!" Doherty admitted. "I feel fantastic! Everything's really cool right now," he added. "I'm enjoying life. People are gonna try and bring you back down, but I'm strong now."
He has also found a new companion in Canadian model, Irina Lazareanu.
"I'm just really (expletive) happy," Doherty said. "I've had many chances. Now life's good."
