Jennifer Nettles will release her first solo album this fall. She's in the studio with super-producer Rick Rubin, who's worked with the likes of Johnny Cash, Adele,Dixie Chicks and Sheryl Crow.

She says, "I am absolutely thrilled and wholly proud to be working with Rick. If you ask any musician who is on their producer ‘bucket list,’ Rick would be on each and every one." 

Jennifer, who's been on maternity leave from Sugarland, will be a presenter at Sunday'sBillboard Music Awards. 

The date has been set for the live TV presentation of The Sound of Music starring Carrie Underwood as Maria Von Trapp. The three-hour event will air on NBC on December 5th -- kicking off the holiday season. 

Carrie says she's thrilled to introduce the classic show to a new generation of fans.
