Brooke Burke -- Cancer Can Kiss My Perky Ass

42-year-old mother of four and cancer survivor Brooke Burke-Charvet knows how to live life to the fullest ... and tightest ... flaunting her ridiculously toned body at a gas station in Malibu today.

Just to recap: this "Dancing with the Stars" badass is 42, she has 4 kids (3 daughters and 1 son) and recently beat thyroid cancer following a scary diagnosis in 2012. And she can still look this good.

FYI, Brooke is currently married to former "Baywatch" star David Charvet.

Gotta love California.
