Britney Spears has reportedly already lost nearly 2stone in weight (26lbs, to be exact) of the weight she gained while pregnant with her two sons.

The star ballooned from 120lbs to 160lbs while pregnant with the boys but since giving birth to her second son, Sutton, just over a month ago she has lost more than half of it.

And according to reports, her weight loss wasn’t a recent of some gimmicky diet or surgery: she’s just working out six days a week and a family friend added: “she is not treating herself with food and desserts anymore.”

Britney is reportedly planning to officially unveil her new figure at an album launch party for her husband Kevin Federline’s debut album later this month. Kevin might be upstaged but probably won’t mind too much: according to his spokesperson, Mike Esterman: “Kevin loves the way Britney looks [now].”
