"It’s all coming from Bill. Whenever he needs a little publicity for a project, he pumps up the so-called controversy between us," he told the New York Times Magazine, adding that there's no real tension.
Takei, who married his husband Brad in 2008, also explained a past story involving his wedding.
When asked about Shatner, 84, calling Takei "psychotic" seven years ago, he responded, "Two months after my wedding, he went on YouTube and ranted and raved about our not sending him an invitation. We had. If he had an issue, he could have easily just phoned us before the wedding, simple as that. But he didn’t. And the reason he raised that fuss two months later is because he was premiering his new talk show, 'Raw Nerve.'"
The 78-year-old actor said any problems the two have date back to the days of "Star Trek."
"It’s difficult working with someone who is not a team player. The rest of the cast all understand what makes a scene work -- it’s everybody contributing to it. But Bill is a wonderful actor, and he knows it, and he likes to have the camera on him all the time," he said.
Takei did say he doesn't need to forgive Shatner and has already invited him to his new musical "Allegiance," which he wrote about his family's struggles during WWII in an internment camp. It will hit Broadway in November.
Shatner's representative did not immediately respond to a request for comment from ABC News.
