Kevin Costner has denied rumors that he is dating singer Jewel, emphasizing that their relationship is strictly platonic. The speculation began after their trip to Richard Branson’s Necker Island in December 2023, where they were seen together with a group of nine people, including Emma Watson. Costner clarified on The Howard Stern Show that he had 'tremendous conversations' with Jewel but no romantic involvement. He expressed concerns that the rumors could harm their friendship, noting that Jewel is 'special' and 'beautiful enough to go out with,' but they have never dated. Costner is focused on his new film, 'Horizon: An American Saga,' and has stated that he is not currently in love or involved with anyone.
