Just because someone has a ton of money, that doesn't mean they tip well. In fact, you'll often find that the richer someone is, the more of a CHEAPSKATE they are.
According to TheRichest.com, here are 10 OF HOLLYWOOD'S WORST TIPPERS:
1. Katherine Heigl: In addition to being a bad tipper, she's also a lousy customer... complaining about her food, sending it back multiple times and being extremely demanding. She's worth $25 million.
2. Sean Penn: He and some friends once ran up a $450 bill at a restaurant in New Orleans, then dashed without leaving SQUAT for the server. He's worth $100 million.
3. Britney Spears: She once threw change at the feet of a valet attendant and said, "There's your tip." She also left a $26 tip on a $500 bill, which comes to 5%. And one time at a Vegas restaurant, she made the waiter run across the street and get her Starbucks. She didn't tip him, or even reimburse him for the coffee. And she's got an estimated $200 million in the bank.
4. Kirsten Dunst: She once left NO TIP on a $223 bill...and after she left, the staff said she was whiny.Another time, a restaurant comped her entire meal and she STILL left no tip. Even though she's worth $25 million.
5. Usher: He's been known to leave AUTOGRAPHED PICTURES of himself instead of cash. He has a net worth of $140 million.
6. Rachael Ray: Being in the food industry, you'd think she'd be a good tipper. But she regularly tips less than 10%, and has even said on her TV show that 7% is GOOD ENOUGH. Maybe that's why she has $60 million to her name.
7. Bill Cosby: He's worth $350 million...but he once left a $3 on a $350 bill. That's less than 1% tip.
8. Jeremy Piven: He was banned from all Nobu restaurants after he took 12 of his friends to one in Aspen in 2007. Even though the place was packed and he didn't have a reservation, they got him a table. He left the Season One DVD set of "Entourage" as a tip, and on the way out, he told the manager, quote, "Thanks for nothing." Piven has a net worth of $15 million.
9. Madonna: She's notoriously rude to waiters and often doesn't leave a tip at all. One time she splurged and left an $18 tip on a $400 bill. That's 4.5%. She's worth $650 million.
10. Tiger Woods: While vacationing with a "mystery woman" in Las Vegas one time, Tiger stiffed his waiter...so the WOMAN left a tip. Probably out of embarrassment. Tiger has $500 million in the bank.
