The “Secret Talents of the Stars” are going to stay that way.

After airing just one episode to terrible ratings, CBS has canceled its new reality show that displayed the secondary talents of B-list stars, such as “Star Trek” actor George Takei belting country songs and country singer Clint Black telling jokes.

That means viewers will never get to see the other so-called stars demonstrate their talents, like Danny Bonaduce riding a unicycle and internet pinup Cindy Margolis performing magic tricks.

“Stars” premiered to a 1.5 adults 18-49 rating and a mere 4.6 million total viewers in its Tuesday 10 p.m. timeslot. It finished well behind ABC’s “Boston Legal” and a rerun of NBC’s “Law & Order: Special Victims Unit” in the slot, while barely beating Univision among 18-49s.

Most alarming for CBS, ratings for the show fell in the second half hour, indicating that the following week’s numbers would be even lower. The network decided that yanking the planned seven-week show early would be the best course.

It will be replaced by “48 Hours Mystery” the next two weeks. On April 29, the drama “Shark” will take over the troubled timeslot, in what could be a preview of next fall’s schedule.

“Shark” had been slated for a tryout in the 9 p.m. spot, but current occupant “The Unit” will remain there instead.

“Stars” becomes the latest CBS program to founder in the 10 p.m. Tuesday slot since the cancellation of “Judging Amy” in 2005. The network has already canceled another show that aired there, the second-year drama “Jericho,” after low ratings.

Many expect last fall’s Jimmy Smits drama “Cane” will also be shelved after slipping below a 2.0 rating in its most recent pre-strike outings.

Other high-profile shows to fail in the 10 p.m. timeslot over the last three years include Ray Liotta’s “Smith,” medical drama “3 Lbs.” and young-skewing dramedy “Love Monkey,” all of which were axed after a few episodes.

“Stars” joins a short list of programs to be dumped after just one outing. The most recent include NBC’s “quarterlife,” a drama imported from the internet that averaged just a 1.6 adults 18-49 rating in its only outing, and Fox’s “Anchorwoman,” which averaged a 1.0 among adults 18-49 in its single episode last summer.

“Stars” was to be a seven-week competition in which viewers voted on which four stars moved on to a final championship round.
