Britney Spears is glowing these days, especially on the cover of InStyle's January 2014 issue.
In a candid interview with the monthly glossy, the pop star reveals how her beauty routine includes getting lip injections -- noting how it's "fun stuff."
"I just bought the new Shiseido face wash and moisturizer. I have no problem trying new brands. A doctor I see, [Beverly Hills plastic surgeon] Dr. [Raj] Kanodia, does fun stuff to me sometimes -- I've had lip injections before," Spears admitted. "He has this peptide-based face-care product; it's green and slimy, and you mix it together and put it on your face. It does wonders. You leave it on overnight. Can you tell I love skin care?"
