"That's kind of breaking news, you can be the first one to say that," the 40-year-old rocker told the publication.
The "Beautiful People" singer said he is back to being himself these days and it helped re-land him his favorite girl, whom he split with in 2008.
"I think that a lot of people will agree that me being me at my best [is what] I need to be. I think that that really paid off because I'm back with Evan," he told the mag of his rekindled romance with the 22-year-old actress.
Rachel was spotted by the paparazzi hanging out with Alexander in Louisiana in September, where the Swede was filming "Straw Dogs."
Alexander was more recently linked to Kate Bosworth, when she was spotted standing near the actor at the GQ Men of the Year Party last month after she presented him with an award. But Alexander shrugged the gossip off in a new interview with Canada's Metro News.
"There's not a single young girl that I know in Hollywood that I have not been paired with," he said. "But that's what happens if I get into a taxi with a girl, suddenly we're married."
