Tiger Woods to Lindsey Vonn -- Hop On, I'll Give You a Ride

Proving he's always got time to help out a hot, blonde chick ... Tiger Woods provided his private jet to injured skier Lindsey Vonn ... so she could fly out of Austria after her devastating crash earlier this week

Vonn -- who's rumored to be Tiger's new "girlfriend" -- boarded the jet in Salzburg this morning.

FYI, Vonn -- whose divorce from ex-husband Thomas Vonn was finalized last month -- has claimed she and Tiger are "just friends" ... friends who share private jets.

As we reported, Vonn was competing at the Alpine World Championships in Schladming on Tuesday when she lost her balance and skidded into a gate ... at top speed. Following the accident, Vonn was airlifted to a nearby hospital where she was treated for injuries to her knee and shinbone.
