Rhys, who reportedly stroked Russell's hair, told the mag last month that he "loves" the rumor.
"That is the best one I love," the 39-year-old actor said at the time, noting that he has to remind his mother that online rumors about him aren't true.
Sources told the New York Post last December that they had seen Russell and Rhys acting "touchy-feely" at a Manhattan eatery.
“Seeing the way they are together I could have sworn they were a couple," a witness said. "They were so touchy-feely, drinking and laughing.”
