"Let me just say, we have made the pivot," Winfrey said today on " Good Morning America." "It's been really an exciting challenge and I am really so happy to announce to the world, 'We have made the pivot.'"

Putting a bounce in Winfrey's step is the year-old network's newest show, "Iyanla: Fix My Life," hosted by Iyanla Vanzant, a best-selling author and spiritual teacher who rose to fame in the 1990s thanks to appearances on "The Oprah Winfrey Show," but saw both her personal and professional lives crumble after a falling out with Winfrey and her daughter's death from cancer.

Winfrey, now on location in New Orleans filming "The Bulter" with Jane Fonda and Forest Whitaker, says the show, which promises to "pull back the curtain" on people's lives, has the signature "A-ha" cache that made Winfrey herself a worldwide star and billionaire businesswoman.

"It has everything that viewers love in a reality show," she said. "[It has] those jaw-dropping moments that cause you to say, 'I can't believe I'm watching this on television,' and it also has everything that I love about the power of television, entertainment plus 'a-ha' moments.

"It is Iyanla at her finest," she said.
