Jennifer Nettles gets back Fab Figure Five Months after giving Birth

New mama Jennifer Nettles is back to her pre-pregnancy shape, just five months after giving birth.

The Sugarland singer surprised everyone at the 2013 Billboard Music Awards at the MGM Garden Arena in Las Vegas, Sunday May 19, by flaunting her slim post-baby figure in a pink outfit designed by Georges Chakra, Us Weekly reported. Rings and earrings from Norman Silverman, a pair of Casadei shoes and a Swarovski bag added to her sexy look.

The country singer, who took a short break after her son's birth, recently announced her plans to release a solo album with producer Rick Rubin in the fall.

"I am absolutely thrilled and wholly proud to be working with Rick Rubin on my new solo album!" Nettles wrote, while sharing the news with her Twitter followers, May 17.

After legally separating with first husband Todd Van Sickle in 2007, Nettles dated Justin Miller for two years and tied the knot in November 2011. The couple confirmed pregnancy in June and welcomed their first child - son Magnus Hamilton Miller - in December 2012.

Nettles revealed her newborn's arrival through a statement posted on her official website: "We are so thankful for all the prayers and support and are excited to take some time together as a new family."

On Mother's Day, May 12, the proud mom, who had kept a low profile since giving birth, introduced her little bundle of joy to the world. "So much love and joy on my first Mother's Day!" Nettles wrote, while posting a picture of her son. "A very Happy Mother's Day to all the Mamas!"

The Grammy Award-winning singer, who started performing at school assemblies, joined Kristen Hall and Kristian Bush to start Sugarland in 2003. In 2006, Hall left Sugarland. In 2008, Sugarland received three Grammy Award nominations and won awards for Best Country Song and Best Country Group/Duo Performance. Nettles was also a judge on ABC's "Duets".
