Popstar Britney Spears, who was recently crowned the biggest star of the past decade, just can't get enough of her diva image as she was reportedly spotted working out with full make-up.

The 28-year-old singer, who is currently dating her manager Jason Trawick wore mascara and lipstick on a recent visit to the gym.

The Toxic hitmaker also sported unbecoming jet-black hair, was on a treadmill and doing crunches at the Mondrian Hotel in Hollywood the other day with her mother, who used dumbbells, New York Post reported.

"Britney worked up such a sweat, she looked like Heath Ledger as the Joker," a witness said.

Celebrity publicists Adam Weiss and Todd Shapiro told Britney, "You're an inspiration" to which she scoffed, "Yeah, right!"
