London, Aug 8 : Britney Spears' sister Jamie Lynn is back to her former slim shape in less than two months after she gave birth to a baby girl.
The 17-year-old showed off her fit figure while taking her little one, Maddie Briann, for a check-up at a Mississippi hospital on Aug 6, reports the Sun.
Jamie is also set to thrill mum Lynn and dad Jamie by marrying fiance Casey Aldridge before the end of the year.
Meanwhile, Britney is also on course for a full-scale comeback.
She has recently bagged an MTV award nomination for 'Best Female Video for Piece Of Me' and is currently working a new album.
