Milburn confirmed to the Daily Mail that she was the woman pictured with Costner but ended the conversation when asked whether they were romantically involved. Neither Costner nor Milburn has publicly confirmed the nature of their relationship.

The connection between Milburn and Aspen has also emerged. She spent nearly six years working for western retailer Kemo Sabe before becoming director of partnerships for Simon Sinek’s The Optimism Company. The former Delta flight attendant has also worked as a local model.

Her social media presence features horses, ranches and mountain properties, reflecting aspects of the lifestyle Costner has established in Colorado.

The actor owns the 160-acre Dunbar Ranch in Aspen, which has 12 bedrooms and eight bathrooms and can accommodate up to 27 guests.
