Tiger is cold as ice.

Erica Herman, Tiger Woods' ex-girlfriend of roughly 6 years, is suing him for $30 million after she claims he "tricked" her into leaving his mansion by telling her to pack for a "short vacation" and then having his people take her to airport ... where they informed her that she was locked out of his sprawling home forevermore and was not allowed to return. 😭

The court docs state, according to BBC:

"Specifically, by trickery, agents of the Defendant convinced the Plaintiff to pack a suitcase for a short vacation and, when she arrived at the airport, they told her she had been locked out of her residence" and "informed her she was not allowed to return."

The docs also say her "personal possessions were removed from the property."

The couple was reportedly in the middle of a messy split at the time. Herman claimed in her suit they had an "oral agreement" that she could live at the mansion for a total of 11 years ... and she still had five years remaining when the golf star booted her.

Woods hit back by claiming there was no such oral agreement, saying Miss Herman is nothing but a "jilted ex-girlfriend" and her "position is utterly meritless."

We all knew Tiger was a stone-cold savage with ice flowing through his veins, but holy moly, this is colder than winning the U.S. Open on one leg. 🥶
