Even though her show will be expiring in two years, that doesn't mean Oprah is receding to the sidelines just yet. She's about to add President Barack Obama and First Lady Michelle Obama to the A-listers she has interviewed over the years on her show. The episode, "Christmas at the White House: An Oprah Primetime Special," will air December 13, and will take audiences behind the White House doors to peek at the holiday preparations. Oprah came out as a loud supporter for the president during his 2008 campaign and was credited with getting him out in the lead for the primaries. It will be Oprah's first sit-down with the man in the White House since he took office.
