Sarah Palin

Sarah Palin's appearance on The Oprah Winfrey Show Monday earned an 8.7 household rating and a 13 share, according to The Hollywood Reporter.

The 2008 Republican vice presidential candidate's interview to promote her book brought in Winfrey's highest ratings since the Osmond family visited her show in 2007, the trade paper reported.

Is Sarah Palin "reloading" for 2012 presidential election?

On the show, Palin discussed Levi Johnston and her highly publicized 2008 interview with CBS anchor Katie Couric as well as her possible run for the White House in 2012. "It's not on my radar screen right now," she told Winfrey.

To promote her new memoir, Going Rogue, Palin also sat down with Barbara Walters. The final part of that interview will air Friday, Nov. 20, on 20/20.
