Maria Shriver: Bold And Beautiful On Oprah's Farewell Spectacular (PHOTOS)

Maria Shriver made a surprise appearance on the 'Surprise Oprah! Farewell Spectacular' Tuesday night at Chicago's United Center. It was her first appearance since learning of husband Arnold Schwarzenegger's affair and love child with former houskeeper Mildred Baena.

RadarOnline.com reported that Shriver may have first learned of the unfortunate news while dining with Oprah, Gayle King and Stedman Graham the night before, at Chicago's RL Restaurant.

Apparently Shriver fielded a phone call during dinner and spent fifteen minutes sorting through her emotions as she learned of her husband's infidelity.

If this is true, we applaud Maria for pulling herself together and helping bid farewell to the media mogul's iconic television show Tuesday night.
