After a surprise on-stage kiss between “The X-Files” co-stars David Duchovny and Gillian Anderson at a New York City show last week, the dating rumors are out there. And with “The X-Files” reboot shoot just days away, both Duchovny and Anderson would have ample opportunity to spend time together on set.

But it sounds like fans will just have to settle for the on-screen romance between their counterparts, Mulder and Scully. In a new interview with TVLine, actor David Duchovny shot down dating rumors between him and his long-time co-star.

“The whole thing about Gillian and I dating is so weird. It’s never happened,” he said. “It’s not going to happen; we’re friends.”

The dating rumors flared up after Anderson crashed an encore during Duchovny’s tour for his new album, “Hell or Highwater.” He dismissed the rumors as overspeculation about his friendly greeting. “I see Gillian. I kiss her hello. She’s my friend. If somebody gets a picture of that, if it’s on stage and she comes up to sing with me, I’m going to kiss her hello,” he told TVLine.

However during a HuffPost Live segment last year, Anderson had a slightly different answer, hinting that the pair once had a romantic relationship that didn’t last after the show was canceled in 2002. She added that the pair got too close over the years and that they shared a genuine spark. "There might even be more than an attraction," she acknowledged. "But it's not going to happen. And it's that frisson that has made it interesting in the series and continues to make it interesting."

"The X-Files" shooting is scheduled to begin June 8 in Vancouver, where hopefully the series will continue the romantic relationship between FBI special agents Mulder (Duchovny) and Scully (Anderson).
