Johnny Depp gave Oprah Winfrey's lucky audience a sneak preview of Pirates of the Caribbean: On Stranger Tides for an episode of the show that aired today. The hot actor also shared a champagne toast with Oprah and showed off a new, shorter haircut during his visit to The Windy City, which took place late last month. Johnny is gearing up for the movie's May 20 release, beginning with Saturday's world premiere at Disneyland. He'll also head to Cannes later this month for the movie's overseas debut. The fourth installment in the Pirates of the Caribbean franchise marks some new beginnings for Captain Jack. It's the first to be filmed in 3D, and also features a new love interest for the swashbuckling hero in Penelope Cruz. We had a chance to talk with Penelope at yesterday's press junket for the film in LA, where she chatted about her longtime friendship with Johnny, dealing with stunts and sword-fighting while pregnant with baby Leo, and how her costars reacted when she did an impression of Jack Sparrow on the set, mustache and all — watch it soon on PopSugar!
