Sugarland’s Jennifer Nettles isn’t ditching Kristian Bush, but she’s signed on to star in the upcoming ABC competition series Duets. She and her fellow judges — Lionel Richie, Kelly Clarkson and Robin Thicke — will travel the country seeking talented duet partners. Each one will pick two singers to bring back to the elimination rounds, who’ll duel in front of a live studio audience.

Duets is set to debut this summer

Eric Church has joined the lineup for Metallica‘s Orion Music and More festival, taking place June 23rd and 24th in Atlantic City, New Jersey. The event features multiple stages, but so far Eric is the only artist representing country music. Other acts include Avenged Sevenfold, Suicidal Tendencies and Cage the Elephant.

Current Forbes cover subject, 41-year-old Sara Blakley is the youngest woman ever to make the magazine’s annual list of billionaires without the aid of an inheritance or her husband.

She owes her wealth all to Spanx, the slimming undergarment she invented after she was frustrated by the way her backside looked in a pair of white pants. Instead of wearing the thick body-shapers available at the time, she cut off the feet of some control-top pantyhose and Spanx were born.

Blakely’s invention has become popular largely based on word of mouth, especially after such stars as Gwyneth Paltrow and Oprah Winfrey let it slip that they wore Spanx to help keep their figures in line. Blakely explained, “It’s the power of the brand. We’ve never formally advertised.”
