A representative for Jive Records stated that although Spears was working in the studio, "no album is scheduled at the moment" and "there are no plans to service 'Mona Lisa' to radio." "Mona Lisa" was released in a bonus CD included with the video of "" (2005), in a rerecorded version with altered lyrics. Spears gave birth to her first son, Sean Preston, on September 14, 2005. In an interview with "People" in February 2006, Spears explained that she was anxious to resume her career, commenting she missed "traveling [...] the road, seeing different places and being with the dancers and having fun. That feeling of being on the stage, knowing it's your best – I love that. I needed a break. I needed to be hungry again." When asked about her next album, she said she had been experimenting in her home studio with live musicians, stripping down her sound and playing the piano. Spears wanted the album to represent her Louisiana roots, explaining that she grew up listening to blues. "When I was little, I would listen to myself [...] But the record label signs you, and you're just thankful to get a hit song. You can't really show off your voice and where you came from. I would like to try to have more influences of that sound. Not that I'm going to be like frickin' Tina Turner. But you never know", she stated. She also said that she hoped the album would reinvigorate the current pop scene, adding that "It's been boring. Nothing's been wow to me." On May 9, 2006, Spears announced she was pregnant with her second child. A few days later, producers such as J. R. Rotem and Sean Garrett told MTV News they were working with Spears. On September 12, 2006, Spears gave birth to her second son, Jayden James. She filed for divorce from Federline on November 7, 2006, citing irreconcilable differences. After the divorce, her partying and public behaviour drew attention from the worldwide media, and ended with two separate stints at Promises Treatment Centers in Malibu, California in February 2007. Her manager Larry Rudolph released a statement on March 20, 2007, saying that she "successfully complet their program."
