“Uncle Frank” Potenza, a regular guest on “Jimmy Kimmel Live!” died Tuesday morning. He was 77.

Potenza was actually the uncle of host Jimmy Kimmel. The nighttime talk show host tweeted: “thank you for your kind words about a very kind man – my Uncle Frank – who passed away this morning.”

Potenza was a New York City police officer for 20 years and has been a regular fixture on the show since 2003.

Playing a security guard on the show, Potenza regularly took part in comedy bits featuring an actual security guard, Guillermo Rodriguez, who works security in the parking lot.

The show’s producers released a statement saying that his “kindness and humor” would be missed.

A cause of death was not released.

Our favorite cute little guidette, Nicole Polizzi a.k.a “Snookie,” from a reality TV show "Jersey Shore" will be gracing the "Jimmy Kimmel Live!" stage on Thursday.

She will sit down with Jimmy to mainly talk about her mega-hit MTV reality show, "Jersey Shore."

Other guests that night include actor Zach Galifianakis ("It’s Kind of a Funny Story") and musical guest Trombone Shorty.

Snooki did “The Late Show” on Tuesday.

“Jersey Shore” is a reality television series launched by MTV last year. It follows eight housemates spending their summers together. All the crazy drama happening among them has made the show utterly successful.

Jimmy Kimmel, in perhaps a coming out party for Mel Gibson, pulled a hilarious stunt on his after-Oscar show.

Gibson, who has largely avoided the spotlight since a 2006 drunken anti-Semitic tirade, appeared on Jimmy Kimmel live and showed an “exclusive clip” from what he and Kimmel played up as his latest top-secret film project about a Civil War officer who loses everything.

That actually got us on IMDB for a second.

Instead, the video shows Gibson coming into his bedroom to see his dying wife surrounded by chickens. She’s clutching “the original recipe.” In a fit of vengeance, he vows that “Kentucky shall fry.” Then we see Gibson with shiny black shoes, a white suit and a black southern tie — Colonel Sanders.

Kimmel also did this hilarious promo with Tom Cruise.

You should also remember last year’s after-Oscar hilarity with a cast of Hollywood A-list stars including Brad Pitt and Harrison Ford singing “I’m fucking Ben Affleck.”
