Dr. Dre just became the richest man in hip-hop — and he's spreading his good fortune around.

Last week, the rapper was partying at West Hollywood's Mondrian Hotel, and when he left, he gave his waitress a $5,000 tip. "She was stunned," a source tells Radar.

But Dr. Dre isn't the only celeb who likes to share his wealth. He joins the ranks of these dozen other big celeb tippers:

Earlier this month, Charlize Theron got Pinkberry in Hollywood, but didn't have cash to pay her $3.75 bill and promised to return. She came back more than an hour later … and gave the employee a $100 bill, letting her keep the change, TMZ reports.

Last year in a Philadelphia restaurant, Taylor Swift not only left a $500 tip — she also gave the head chef two tickets to her show the next night for his son, a big Swift fan, the New York Daily News reports.

Brad Pitt, Angelina Jolie and their kids ordered $1,000 worth of food at a Japanese restaurant in Berlin last year — nearly everything on the menu — and then left an $846 tip, Entertainmentwise reports.

In 2011, Jessica Simpson tipped 60 percent on a $500 restaurant bill at Lavo in New York, and also left her waitress a note telling her she makes the world "a better place," the Daily News reports.

At a Welsh pub in 2009, Russell Crowe left a $1,000 tip on a $400 tab — and played an impromptu set with his band, Hello reports.
