Not a big tipper? Gwen Stefani flashes a whole $10 as she approaches a valet stand outside pricey Beverly Hills restaurant The Palm

She looked like a million dollars as she left The Palms restaurant in Beverly Hills on Wednesday night after dinner with friends.

But in Gwen Stefani's hand was a measly $10, most likely for some overworked valet attendant.

The 45-year-old Rich Girl hit maker is reportedly worth $100m.

In her usual quirky style, the mother of three wore black spike-studded ankle boots and fishnet tights, a pair of loose green, navy any yellow tartan shorts, a black and white polka-dot blouse under a navy coat.

Her molten gold purse was clutched under her arm to finish the outfit off.

As always, her ever present vivid red lipstick corralled her gorgeous smile, framed by her trademark pale complexion and platinum blonde tresses.

But all eyes were on the baller roll of notes brandished by the star which consisted of at least five singles and even a five.

Sadly for the valet, the wad of cash didn't stay quite so fat before it made its way into his pocket. Careful so as not to overpay, Gwen appeared to frugally peel off one of a solitary $1 bill before folding the remainder into the not-so-generous tip.

At least the Hollaback Girl wasn't so stingy with her time.

As she emerged from the eatery, a number of fans approached and asked if she would pose in selfies, and she happily obliged.
