Guillermo Rodriguez^[2] (born January 27, 1971)^[3] is a Mexican-American^[4] talk show personality best known as the sidekick for American late night talk show Jimmy Kimmel Live!. He rose to fame while working as a parking lot security guard at the Hollywood Boulevard studios. ^[5] He continues in character and title as the show's security guard.

Rodriguez was born in Zacatecas, Mexico.^[1]

Rodriguez began working as a parking-lot security guard for Jimmy Kimmel Live! studio in 2003.^[6] At that time he also had a second full-time job as a hotel room server as well as working weekends at a third.^[7] After he was caught sleeping in announcer Dicky Barrett’s car, Kimmel offered to have him appear on the show.^[8] Due to his shyness at the time Rodriguez initially turned down the offer to appear on the show in 2003 but was talked into it by one of the producers.^[7][9] His early appearances were with "Uncle Frank" Potenza in a series of bits called "Security Night Live".^[10][11] (Potenza had originally handled security for the show before his role was expanded to appear on screen.)^[11] Rodriguez soon moved to acting in skits on the show with his first role being Michael Jackson's Spanish cook. His broken English coupled with his affability and teddy bear-like quality earned him a high-profile supporting role as a personality on the show, in which he usually plays the Everyman.^[10] Guillermo took over main red-carpet interviewing duties in 2011 after Potenza died. ^[5]

Rodriguez is married. He and his wife have a son named Benji who was born on December 11, 2011.

He became a U.S. citizen in 2005.^[12]
