Britney Spears drops more weight

When the 25-year-old singer emerged from rehab less than three weeks ago she looked bloated and out of shape.

But on a shopping expedition in Los Angeles she showed off a remarkable return to her previous svelte form reports Daily Mail UK.

She giggled as she repeatedly toyed with the hem of her short dress, pulling it up time and again to give a glimpse of her legs.

Britney Spears' dramatic transformation as she moves to relaunch her flagging music career - prompted speculation that she may have had more than a little helping hand to get herself trim.

A week ago she was spotted emerging from a cosmetic surgery clinic already showing signs of losing the pounds she had put on since splitting from her husband Kevin Federline last year.

A source told the American magazine Star: "Britney wants to look better than she ever has in her life. She has a plan and has already started working on it."

"She is a size 6 (UK size 10) and wants to be a size 2 (UK size 6) when she is done in three months."

She is said to have paid an hour-long visit to the LipoDissolve Center in Las Vegas, where she was reportedly tempted by the clinic's liposuction-like treatments for the face, legs, stomach and bottom.

Miss Spears, who has denied having liposuction, has also reportedly consulted a plastic surgeon about possible surgery.
