Lindsey Vonn finds cracks in Tiger Woods' sinking home

Tiger Woods might have finally fixed the cracks in his once-slumping golf game but it was his new girlfriend, Lindsey Vonn — along with the golfer — who found them in his Florida home. And we're talking physical breaks in the house and not in their budding relationship.

While Woods is busy sinking putts to earn his first major win in more than five years this weekend at the PGA Championship, his Jupiter mansion may be getting swallowed up by the sandy Florida soil.

An insider tells Gossip Extra exclusively that Woods' current gal Vonn noticed cracks in walls and doors rubbing on the ground, sure signs of trouble in the future.

According to public records in Martin County, Woods is having a contractor shore up his 10,000-square-foot modern crib. 

"This sort of thing occurs quite a bit in Florida," Skip Barrett of South Coast Foundation Systems said. 

"In Florida, the soil has layers of organic matter that eventually decomposes. Once that happens, many homes start sinking."

A contractor is about to attempt to stabilize the structure by inserting giant screws called “helical piles” as far as 24 feet into the ground that cost an estimated $1,000 apiece. 

The site says a home the size of Tiger’s would require 15 of the piles, but fortunately Woods won $1.5 million at last week’s Bridgestone Invitational, so that shouldn't put a dent in the couple's budget plans.
