Although we have some better examples for age factor but Britney Spears can be quoted as well. She almost turning 31 and is mother of two kids Sean Preston and Jayden James but shows no sign of having given birth to two children or of aging. Here when she stripped down to a white bikini in we held our breath.

The pop star said that she shed 20 pounds, thanks to two-hour cardio-and-strength-training workouts three times a week (on top of dance rehearsals).

Before you comment anything in this set let me tell you that this gallery is not very current but these pictures never surfaced internet in nice quality so when i finally got them from a friend who is a photographer and big fan of Britney Spears i decided to publish them.
