Rosie O'Donnell Takes Over Oprah's Studio, 'Mad Men' Return Pushed to 2012 and More

Rosie O'Donnell is taking over Oprah Winfrey's stomping grounds. O'Donnell will tape her new OWN daytime talk show on Winfrey's sound stage when the daytime queen ends her reign on May 25.

Yes, O'Donnell is heading to Chicago. "There is an enormous personal respect and value to that little bit of real estate to Oprah," Sheri Salata, president of Harpo Studios, told the Chicago Sun-Times. "I think it's safe to say they have an excellent relationship."

O'Donnell made the announcement to Harpo staffers via video.

The new series will be less celebrity-driven than O'Donnell's previous daytime gig. Instead, the series will tackle real issues that affect everyday people.
