Oprah Winfrey is known for springing big surprises on her guests and viewers. And as we can see in this exclusive ETOnline clip, the Queen of Talk recently struck again by paying an unannounced visit to the St. Louis soul food restaurant Sweetie Pie's, which is featured in its own reality series on OWN.
Oprah's impromptu visit was made possible because she was in town for a live taping of her popular series Oprah's Lifeclass: the Tour.
Her surprise visit will be featured on this Saturday's all-new episode of Welcome to Sweetie Pie's, which features Robbie Montgomery -- a former backup singer for Ike and Tina Turner and the Beatles -- and her family as they operate the famous St. Louis eatery.
Watch the video to see the stunned reactions of the Montgomery family and others when Oprah suddenly appears and be sure to catch Welcome to Sweetie Pie's this Saturday at 9 p.m. on OWN.
