CBS won't air 'NCIS' next Tuesday night

"NCIS" fans were disappointed to learn that their favorite show was pushed aside for a reality TV show.

CBS did not air "NCIS" during its usual time slot on Tuesday night. Instead, they replaced it with a new episode of the competitive reality show "Celebrity Big Brother."

Fans of "NCIS took to Twitter to express their grievances about the unexpected switch-up. They will be even more annoyed to find out that the same thing is happening next week.

Another episode of "Celebrity Big Brother" will air on January 29. "NCIS" is set to return to its usual slot on Tuesday, February 5.

While they might be upset now, fans can expect brand new episodes of the action police series. In an upcoming episode entitled "She," they'll see the team investigate the case of a young girl.

According to PopCulture, Bishop will lead the search for details about the nine-year-old who they believe is a Navy recruit's daughter.

She disappeared as a young girl, however. Notes left behind from former Special Agent Ziva David help in their investigation.

Meanwhile, "Big Brother" fans can look forward to seeing the new celebrity-filled cast showdown on Tuesday. Actors Jonathan Bennett and Joey Lawrence, Lindsay Lohan's mother Dina Lohan, and singer Tamar Braxton are just a few of those who make up the new cast.

Tuesday night's episode saw Bennett and Olympian John Lochte win the first competition. Afterward, host Julie Chen said the pair would be separated for the upcoming episode.

Back in November 2018, fans of "NCIS: Los Angeles" were delighted to hear of the possible return of a beloved character who was the victim of a car accident in July.

Actress Linda Hunt, who played Henrietta "Hetty" Lange on the show, hinted at a comeback in a statement she released to fans. The Academy-award winner has been part of the show since its start in 2009.
