This new relationship is developing rapidly for Costner, especially considering that he only recently finalized his contentious divorce from Baumgartner in September of this year.
From TMZ:
Here's what we know. The 2 flew to the Caribbean together and hung out a lot for more than a week. As one source put it, "There was definitely something going on. They were flirty, and when they were together, it was like they both just lit up."
One source added, "You could tell they were trying to be discreet, but anybody who saw them could tell something was going on."
Jewel had mentioned Kevin on social media, talking about the event, writing ... "it's an incredible time, and one I use to relax, rest and play w my son! @kevincostnermodernwest was kind enough to mentor our kids this year."
They played doubles with Sir Richard, who, as she says, "plays a mean game!"
We're told the 2 also flew back together.
This union comes off as somewhat unexpected to me, but considering the rocky marital histories of both Costner and Jewel, one can hope that their shared experiences have equipped them with the clarity to discern what they truly desire.
Congrats to the new couple!
