Costner also has older children from his previous marriage to Cindy Silva and a relationship with Bridget Rooney. Costner and Baumgartner attended red carpets together during the most recent awards cycle. "How beautiful is my date?" Costner posted on Instagram after they appeared at the Oscars. Amid this personal turmoil, his professional career may also be in a state of transition. Fans of Yellowstone, the hit TV series starring Costner as Montana ranch patriarch John Dutton, were shocked by February reports claiming the actor might leave the popular Western to focus on film. Paramount told EW at the time that Costner is "a big part of Yellowstone and we hope that's the case for a long time to come." Yellowstone's Wes Bentley told EW later that month at SCAD TVFest that "it's probably a bit of drama over nothing." All that said, there are still no updates on when the second half of the show's fifth season is supposed to air.
