It was a feud that no one saw coming -- but that Tom Bergeron is hoping to squash!

Following Shatner's unexpected shade toward Nick Viall's Dancing With the Stars debut on Monday night -- during which he encouraged fans to vote for anyone but the former Bachelor -- Bergeron is trying to play peacemaker.

Shatner has yet to reply to Bergeron's request, though judging by his Twitter rant on Monday, this beef isn't going anywhere.

"He needs to go next week!" the 86-year-old demanded, explaining that Viall "lives up to the homonym of his last name," and telling users to "Watch Andi’s Bachelorette Season where he started this Viall journey."

"Leopards don’t change their spots," Shatner wrote as some came to Viall's defense. "Don’t be surprised if he shows up again on Paradise. I won’t be."

Both Viall and Murgatroyd (whom Shatner doesn't seem to have any issue with) took to Twitter to respond to the Star Trek star's smear campaign. See their reactions in the video below.
