George Takei's long-running feud with William Shatner has been taken to new heights.
The "Star Trek" actor blasted his former costar after his trip to the edge of space aboard Jeff Bezos' Blue Origin capsule.
"He's boldly going where other people have gone before," George told Page Six after the Capt. Kirk actor landed back on the ground in the West Texas desert. "He's a guinea pig, 90 years old and it's important to find out what happens."
On Oct. 13, Shatner and the three others aboard Blue Origin experienced four minutes of weightlessness before the space capsule headed back to earth. At the age of 90, the "Star Trek" icon is now the oldest person to ever go to space.
George wasn't all that impressed, calling the "T.J. Hooker" star "very self-centered."
"So 90 years old is going to show a great deal more on the wear and tear on the human body, so he'll be a good specimen to study," he said. "Although he's not the fittest specimen of 90 years old, so he'll be a specimen that's unfit!"
There's been bad blood between the two men for decades.
Upon hearing George's take, the newly-minted astronaut said, "There's a psychosis there … There must be something else inside George that is festering, and it makes him unhappy that he takes it out on me … Why would he go out of his way to denigrate me? It's sad, I feel nothing but pity for him."
