10 prolific TV talents, seemingly everywhere

WE'RE NOT SAYING these are the 10 busiest people on television - last we heard, Dr. Mehmet Oz ("Dr. Oz") was still cracking open people's chests - but in an age of high unemployment, all these people are highly employed:

What he's up to on air: Regular hosting duties include Fox's "American Idol," which made him a household name; a nationally syndicated radio show, "On Air with Ryan Seacrest"; and "E! News."

Behind the scenes: One of cable's most prolific producers, Seacrest, 37, is one of the people responsible for "Keeping Up with the Kardashians" (and its various demon offspring). His company's latest show, "Shahs of Sunset," about young Persian-Americans in Los Angeles, premieres at 10 p.m. Sunday on Bravo.

Hot property: With his "Idol" contract up for renewal this year, both Fox and Comcast-owned NBC Universal (which includes E!) are eager to keep him in their respective families. He's been mentioned as a possible replacement for Matt Lauer on NBC's "Today" show, should Comcast not back up the truck to keep Lauer, but NBC's programming chief, Bob Greenblatt, has also said he'd be interested if Seacrest wanted to do "interview specials à la Barbara Walters."

What she's up to on air: Host of E! late-night talk show "Chelsea Lately," the 37-year-old comedian also plays herself on its mockumentary companion series "After Lately" and appears on NBC's sitcom, "Are You There, Chelsea?" playing her own older sister.

Behind the scenes: She's the boss. She's also written several best-sellers - including Are You There, Vodka? It's Me, Chelsea, which inspired the NBC show - and now has her own publishing imprint.

Not finished just yet: Though she says "less is more" and "I'm good" for now, Handler can envision a future where she might get more than six minutes to interview a guest, including perhaps some of those specials NBC's talked of for her E! colleague Seacrest. "But I'm not going to compete with Ryan, since he's my sister," she joked recently. "He's got seniority over me."

What he's up to on air: Longtime mentor on Lifetime's "Project Runway," he recently added a five-day-a-week gig at ABC, where he's one of the co-hosts of its daytime show "The Revolution."

Behind the scenes: Gunn, who was the fashion design chair at Parsons The New School for Design until 2007, is now the chief creative officer for Liz Claiborne. He's also written three books, including a 2011 memoir, Shaken, Not Stirred.

Late bloomer: When "Project Runway" came along, said the 58-year-old Gunn, "I was thinking about that cabin in the woods. All this happened to me after I turned 50. How remarkable is that?"

What she's up to on air: Nash, who's been both a "reality" star ("Clean House") and actress ("Reno 911!") is still playing both sides of the street, with a TLC "docu-sitcom" about her newly blended family, "Leave It to Niecy," premiering March 25, and "Have Faith," a TV Land sitcom spin-off of "Hot in Cleveland," coming in June, in which she'll be the wife of a preacher played by Cedric the Entertainer.

If that's not enough: She has a web series on Yahoo, "Let's Talk About Love," "about love and relationships," she said. "And then I have my HSN deal, which is launching in April," and she's writing a book. "And I'm a new wife. That's another job!" Along with her own three children, she now has a stepson.

What she says to "Clean House" fans who still want her to de-clutter their homes: "I'm not doing that show now, but I never say never [about returning]. Because I really do like helping people."

What he's up to on air: Hosts a nightly show, "Anderson Cooper 360°" (8 p.m., CNN) as well as a syndicated daytime show, "Anderson" (9 a.m., CBS 3). He's also a contributor to CBS' "60 Minutes."

Offscreen: The 44-year-old Cooper, who's never minded crossing the supposed line between news and entertainment - he used to host ABC's "The Mole" - can be heard as the (prerecorded) voice of the narrator in Broadway's latest production of "How to Succeed in Business Without Really Trying," a gig held by Walter Cronkite in a previous revival of the show. Oh, and like most journalists, he has a blog: http://ac360.blogs.cnn.com.

What she's up to on-screen: The "Saturday Night Live" veteran stars in NBC's "30 Rock" and in the occasional movie ("Date Night"). You can check out her Sarah Palin impression one more time on Saturday in clips shown during HBO's "Game Change," in which Julianne Moore plays the former vice presidential candidate. And then there's her latest gig, pushing hair color for Garnier Nutrisse.

Offscreen: Creator and executive producer of "30 Rock" - which means the 41-year-old Upper Darby native is boss to both Tracy Morgan and Alec Baldwin - she's also a best-selling author. Gave birth in August to the second of her two daughters.

What he's up to on-screen: Hosts Bravo's late-night show "Watch What Happens: Live," which recently expanded to five days a week, Sunday through Thursday.

Didn't quit his day job: As executive vice president of development for Bravo, the 43-year-old Cohen is the suit in charge of, among other things, "The Real Housewives" franchise.

On how he keeps up his energy: "I'm very passionate about what I do and I love what I do. And I try to work out five days a week."

On-screen: Stars in NBC's "Whitney."

Behind the scenes: The 29-year-old University of Pennsylvania grad, actress and comedian created two of this season's new sitcoms, "Whitney" and CBS' "2 Broke Girls" (with "Sex and the City" writer Michael Patrick King).

So she's highly employed?: "I'm highly tired, yes."

How she's juggling shows on two different networks: "I still read scripts [for '2 Broke Girls'] and, you know, pitch whenever I can, but the majority of my time is obviously spent on my NBC show, since I'm in it. But Michael Patrick King is the best at this, at writing for girls and running a TV show about women and their sex lives and stuff, so it's in very good hands. I miss it every day."

What he's up to on-screen: Co-host of the new "CBS This Morning," he's still hosting his long-running PBS late-night show, "The Charlie Rose Show" (midnight, WHYY 12) as well as occasional "Person to Person" specials for CBS.

Why, at 70, did he add a morning show to his schedule?: "I'm a morning person. . . . Morning television sets the agenda in a way."

A couple of things he thinks viewers might not realize: "No. 1, I'm an early riser, as I have been, and a year ago I got up at 5 o'clock in the morning every morning, between 5 and 6. I continue to do that. No. 2, my program on PBS is shot at 5 o'clock. It's not live at 11 o'clock."

Not to worry: "I would not have done this if I had any reason to believe it wasn't doable and any reason that it would affect the hundred years that I expect to live," Rose told reporters in January.

What she's up to on-screen: Co-stars with her daughter in the WEtv show "Joan & Melissa: Joan Knows Best?" The pair are also co-hosts on E!'s "Fashion Police.

Offscreen: Rivers, 78 and still going strong - and, yes, still going under the knife periodically - continues to work regularly as a standup comic.

Someone tell the Brits: She's touring the United Kingdom later this year.
