On Monday, Aug. 7, the Yellowstone actor and his 13-year-old daughter Grace were seen in a SoFi Stadium VIP suite for Taylor Swift's Eras Tour.
Page Six film showed the two dressed up and rocking out while Swift performed her songs, including "We Are Never, Ever, Getting Back Together" from Red.
“I’m really going to miss you picking fights / And me falling for it screaming that I’m right / And you would hide away and find your peace of mind / With some indie record that’s much cooler than mine,” Swift belted from the stage. “Never again.”
Most of the clip shows Costner's daughter enjoying time with dad, while he appears unbothered.
The father-daughter pair's big night out comes only weeks after Costner's former wife and Grace's mom, Christine Baumgartner, was photographed moving out amid their painful breakup.
Baumgartner, 49, filed for divorce from Costner in May, alleging irreconcilable differences.
The two had been fighting over property, finances, and child support for most of the summer until a judge ruled last month that Costner must pay Baumgartner $129,755 per month in child support
half of what she had originally requested to help pay for the couple's kids, Cayden, 16, Hayes, 14, and Grace—and that Baumgartner must leave Costner's home by July 31. She left with a UHAUL truck a few days later.
