Lisa Vanderpump Accidentally Shows Her Vander-Panties

Talk about a wardrobe malfunction!

Lisa Vanderpump grabbed dinner at BOA Steakhouse in Hollywood last night, and the Real Housewives of Beverly Hills star wore a skintight white dress that required some Spanx... which she flashed us when she got out of the car!

The reality star is at the center of some serious drama these days! According to reports, the British beauty and her bestie Brandi Glanville recently confronted their co-star Kyle Richards about rumors that her husband Mauricio had been cheating, and the cameras were rolling for the whole thing!

We can't wait to see how all the drama unfolds on the new season!
