TIGER WOODS angrily booted girlfriend LINDSEY VONN out of his palatial Florida home after she chastised his young children.

But an insider says that the skirt-chasing golfer is using Lindsey’s run-in with the kids as an excuse to get her out of the picture – because he’s already tired of her and ready to find someone else!

The face-off  took place at Tiger’s $55 million mansion in tony Jupiter Island, Fla., after his daughter, Sam, 5, and son Charlie, 4, swiped some of Lindsey’s clothes and jewelry and pranced around in an in­nocent game of dress-up. But instead of playing along, a source said champion Olym­pic skier Lindsey chastised the kids, and “right away, Tiger knew this was trouble.”

Tiger, 37, told Lindsey, 28, that they could keep seeing each other, but it was time for her to leave, and a tearful Lindsey began pack­ing. “It’s over, and Lindsey knows it,” a source told The ENQUIRER. “Tiger wants out.”

Tiger’s ex, Elin Nordegren, who divorced Tiger in 2010 af­ter The ENQUIRER revealed he’d been hooking up with New York party girl Rachel Uchitel, was already furious that Tiger let Lindsey around their kids.

“Elin said, ‘The kids don’t need to see women come and go in his life,’ ” said the source. “ ‘I know him too well – Tiger will get bored and she will be history.’ ”

And that’s exactly what’s happening, says the source.

“Lindsey was never the one for Tiger. She’s miserable, but there’s nothing she can do about it.”
