Rowland says: ''There's a young guy that came in by the name of Josh Levi and he is a little beast. And he's so young. He's 14 years old and just as cute as he can be. You just want to kiss him on his little face and he opens up his mouth to sing and his range is crazy.'' —Lindsey Bahr

6 of 9
Premieres: Friday, Sept. 27, at 8 p.m. on CBS
What to expect: In the fifth season of this heartwarming reality series, there's still new territory for these disguised bigwigs to explore. For the first time, the show will venture into the world of New York fashion.
Executive Producer Chris Carlson says: ''We haven't really seen retail fashion before. That's a really great, relatable world that everyone deals with on a daily basis. The boss there is really interesting. He's our first openly gay boss, not that that's a huge deal. He gives us a point of view and a character type we haven't seen. He's a New Yorker, he's really kind of hip and fast-moving, and he's very demanding as you would sort of imagine, stereotypically, in the fashion business.'' —Stephan Lee

What to expect: Gordon Ramsay is not going to hold back with his critiques of the 24 kids ages 8 to 13 competing for the title of Junior Masterchef. Whether making fresh pasta or taking over a fancy restaurant, the kids stay positive and eager to learn.
Executive Producer Robin Ashbrook says: ''The kids all love each other. In the grownup show when someone is eliminated that's one less person who's standing in the way of you winning $1 million. The kids? They're just sad when all the others go. They just wanted to stay and hang out with each other.'' —Lindsey Bahr

The Biggest Loser
Premieres: Tuesday, Oct. 8, at 8 p.m. on NBC
Stars: Alison Sweeney, Bob Harper, Jillian Michaels, Dolvett Quince
What to expect: In addition to slimming down to one hour, the weight loss series is squeezing out more tears from contestants in addition to sweat. The ''second chances'' theme this season will ensure emotional backstories — including that of American Idol winner Ruben Studdard, who begins the season as the heaviest contestant.
Executive Producer Lisa Hennessy says: ''We added a device this year which we've never done before, which is the trainer save, so they not only pick their teams, they have the ability to at certain points in the season save contestants on their team, so it's just kind of a little twist in keeping with the second chance theme.'' —Stephan Lee
