KEVIN SOWING WILD OATS - AGAIN

Old-timer frisky with the fillies

FLIRTY geezer Kevin Costner is gleefully chasing younger ladies — and boasting that he's never had so much fun at the ripe age of 70, according to sources who say concerned pals are urging the former Yellowstone cowboy to rein in his embarrassing behavior and stop acting like a randy Romeo.

The screen stud was spotted chatting up a mystery brunette last month at West Hollywood hot spot Raspoutine.

“It’s clear he’s going through a midlife crisis,” an insider observes. “First came the surgery and the vanity treatments, now he’s bed-hopping and having his share of booty calls.”
