Adam Lambert Sits Down with Oprah

It's hardly like Adam Lambert to be anything but upfront, so the recent mystery about his possible appearing with Oprah Winfrey on her show was a bit baffling. But baffle no more.

While the American Idol sensation addressed the rumors and Twittered last Thursday, "Oprah: def true," word from the Winfrey camp said that the 27-year-old and the media queen taped their interview Wednesday at the Harpo Studios in Chicago. The show will air Tuesday, January 19th.

In the course of their sit-down, Lambert – sporting a new haircut – touched upon Simon Cowell's announced departure from Idol and its possible ramifications for the show, what life was like for him both pre-Idol and after, and his controversial performance at the American Music Awards.

The singer also performed "Whataya Want from Me" from his new album For Your Entertainment.

Also appearing on the Oprah Winfrey Show with Adam is chart-topper Susan Boyle.
