Oprah Winfrey plans to end her daytime talk show late in September 2011 — but she won't be off the air for long.

The talk show host, 56, announced Thursday in New York City that she'll star in a nighttime talk show, Oprah's Next Chapter, on her OWN network, sometime in late 2011.

Instead of working in a TV studio, "I'm going to take viewers with me, going to take celebrities I want to interview with me [around the world]," Winfrey told the Wall Street Journal of the series, which will air two to three times a week.

Shania Twain
, 44, will also star in a one-hour series called "Why Not?" about her life after splitting from her husband of 14 years in 2008. (She's been dating Frederic Thiebaud. Thiebaud's ex wife, Marie-Anne, had an affair with Twain's husband Robert "Mutt" Lange.)

BFF Gayle King will bring her radio show to TV, with a daily talk show called Gayle King Live!

A weekly show called Visionaries: Inside the Creative Mind will follow stars like James Cameron, Lady Gaga and designer-director Tom Ford.

Oprah Presents: Master Class will feature stars like Jay-Z, Simon Cowell, Bono and Condoleezza Rice offering life lessons.

“My vision for OWN is to create a network that inspires our viewers and makes them want to be who they are on their best day," Winfrey told the WSJ of the new programming, which kicks of Jan. 1, 2011.
