Rosie O’Donnell’s next stab at headlining a talk show debuts tonight on the Oprah Winfrey Network.

Discovery Communications, the Silver-Spring-based company that co-owns the new-ish network with Oprah’s Harpo Productions, is taking no chances and will simulcast “The Rosie Show” not only on OWN but also across four other Discovery networks — including the company’s too-many-kids-reality-series flagship network TLC. Also pitching in are Investigation Discovery, Discovery Fit & Health, and Planet Green.

Rosie — who had her own syndicated talk show in the late 90’s and early 00’s — and in late ‘06/early ‘07 famously flamed out after less than one year as moderator of ABC’s daytime chatter, “The View” — has been out promoting her return to the talk show circuit. That includes a phoner she did recently with The Reporters Who Cover Television in which she assured them that, now that Oprah is devoting her attention full-time to the new network (because her syndicated show is wrapped) and she, Rosie, is on board, “It’s going to be a huge hit like everything else [Oprah] touches.”

(Rosie also said she’s invited her most controversial guest from her old late-90’s syndicated talk show, Tom Selleck to be a guest on her new program, which will run at 7 p.m. ET, Monday through Friday. If you watched that particular episode, which aired not long after the mass shootings at Columbine High School in suburban Denver, Rosie went for Selleck’s jugular for his support of the National Rifle Association and and Selleck, in turn, called her “stupid.” Great TV. She’s not sure if he’s going to accept the invitation.

Rosie’s show, which will be shot from Oprah’s old talk show studio in Chicago, has been positioned at 7 as the feeder stream for OWN “Oprah Rerun Theatre” at 8. Yes, it’s going to be repeats of Oprah’s syndicated talk show — but so much more. That’s because it will also include updated musings from Oprah about her favorite moments and lessons from over the years.

And, in case one hour with Oprah is not enough, she will be host live discussions each night this week on her Facebook page, after the show.
