Petra Ecclestone may be a billionaire, but that doesn't mean she needs to run out of the house totally done up.

The Formula 1 heiress ran errands around Los Angeles Thursday afternoon, stopping at a hair salon before shopping at the Sephora store in the Century City Westfield Mall. She finished off her day of spending by grabbing an Iced Blended drink to go from the Coffee Bean & Tea Leaf in Beverly Hills.

Even though Petra went sans makeup, she still showed signs of her very well-to-do life, toting around her pricey neon yellow Birkin bag all day.

Not too shabby!
