COSTNER'S WIFE FLAUNTING HER FREEDOM!

But Kevin is crushed by their divorce

HEARTSICK Kevin Costner is a broken man after being blindsided by divorce papers from Christine Baumgartner — but the Yellowstone hunk’s estranged spouse is only too happy to ride off into the sunset without him, insiders squeal.

Beautiful Christine, 49, was beaming in Santa Barbara as she ran errands without her wedding band — just two days after her filing blamed “irreconcilable differences” for ending the couple’s 18-year union!

“It’s very obvious Christine couldn’t wait to rip off that ring and parade herself around with a cheesy grin,” tattles an insider.

“She may as well be holding up a placard to Kevin telling him to eat her dust!”
