KEVIN'S WIFE RUBS HIS NOSE IN IT!

Plays in paradise with his pal after scoring $1.56M in divorce battle

- 

HUMILIATED Kevin Costner was blindsided by a nasty surprise amid his $400 million divorce showdown with estranged wife Christine Baumgartner — the gleeful gal was caught on camera enjoying a Hawaiian getaway with the Yellowstone cowboy’s divorced buddy, sources squeal.

Days after a judge ordered Costner, 68, to pay the 49-year-old handbag designer nearly $130,000 a month in child support — $1.56 million annually — for the couple’s kids, Cayden, 16, Hayes, 14, and Grace, 13, carefree Christine was seen soaking up the sun during play days in paradise with shirtless stud Josh Connor! 

“Kevin had to pick himself up off the floor after seeing what Christine was up to with one of his closest friends,” an insider tells The National ENQUIRER. “I don’t think he’s ever been so embarrassed.”

Moles say the red-hot mama took her three teens along for the lavish vacation on the Big Island — and the father-free family stayed at the same ritzy resort as Costner’s wealthy financier pal!
