Jimmy Kimmel is reportedly taking aim at Jay Leno once again in a new interview.
The late-night talk show host talked about Leno during his interview with Rolling Stone where he reportedly says Leno "sold out."
"Leno hasn't been a good stand-up in 20 years," Kimmel said to Rolling Stone, according to The Hollywood Reporter.
"As a comedian, you can't not have disdain for what he's done," he added. "He totally sold out. He was a master chef who opened a Burger King."
Kimmel's full interview with Rolling Stone is not available online yet but the preview for the story alludes to Kimmel talking about "his undying hatred of Jay Leno." Kimmel appears on the cover of the magazine dressed as a plumber exposing his behind.
Kimmel is gearing up for a time slot change for "Jimmy Kimmel Live!," which will shift on January 8 to airing at 11:35 p.m., putting it in direct competition with Leno's "Tonight Show" and "Late Show with David Letterman."
This is not the first time Kimmel has taken a swipe at Leno. The comedian impersonated Leno on "Jimmy Kimmel Live!" in 2010 during the NBC late night drama between Conan O'Brien and Leno. Kimmel also appeared on Leno's primetime show where he bashed the host during an interview.
In one example, Leno asked Kimmel, "Ever order anything off the TV?"
To which Kimmel replied, "Like NBC ordered your show off the TV?"
David Letterman, who Kimmel has said in the past was his childhood idol, calls Leno "insecure" during an interview with Oprah that is set to air and January 6.
"He has a way ... he's an unusual fellow," Letterman told Winfrey. "I've never met anyone quite like Jay and I will say and I'm happy to say that I think he is the funniest guy I've ever known -- just flat out ... if you see him do his nightclub act, just the funniest, smartest, wonderful observations and very appealing as a comic. Therefore, the fact that he is also maybe the most insecure person I have ever known, I could never reconcile that."
Letterman and Leno have their own feud going back as far as when Leno was named the permanent host of "The Tonight Show" over Letterman in 1992.
Kimmel's issue of Rolling Stone hit newsstands on Friday, January 4.
