and War and subsequent releases In 2006, Stone appeared on the VH1's reality television series Celebrity Fit Club for the fourth season, which began on August 6, 2006. While on the show, she lost eighteen pounds, the second lowest loss in the history of the show. The same year, Stone signed to the reworked Stax Records. Her fourth studio album The Art of Love & War, a reference to her experiences in her final days at J Records, where it had become expected that she would help develop new talent, was released on October 15, 2007. The album debuted at number eleven on the US Billboard 200, selling 45,000 copies in its first week, becoming Stone's highest-charting album to date, as well as her first and only album to date to top the Top R&B/Hip-Hop Albums chart. Lead single "Baby", a duet with Betty Wright, became her second number-one hit on the US Adult R&B Songs and earned Stone her third nomination at the 50th Annual Grammy Awards. Stone's second effort with Stax Records, her fifth studio album Unexpected, was released in November 2009. With its title partly referencing Stone's sudden and devastating loss of her father who unexpectedly died in the midst of her recording sessions for the album, it marked a slight move away from Stone's signature sound in favor of more upbeat R&B and funk influences. A commercial failure, the album debuted and peaked at number 133 on the US Billboard 200 and failed to chart elsewhere. "I Ain't Hearin' U", the album's lead single reached number 14 on Billboards Adult R&B Songs. In 2009, Stone had a minor role as a strip-club owner in Rockmond Dunbar's comedy drama Pastor Brown. Also that year, she sang "Wade in the Water" in the civil rights documentary Soundtrack for a Revolution (2009). In 2010, Stone then played the head matron of an all-girls school in the film, School Gyrls (2010), directed by Nick Cannon, which featured many Def Jam artists. Along with NeNe Leakes, Stone co-starred in the play Loving Him is Killing Me that was performed in Washington, DC, Miami, and Philadelphia in May 2011. The play was written by Theo London and also starred Tyson Beckford and Christopher Williams. In 2012, Stone signed to Saguaro Road Records, an in-house music recording label of Time-Life, and released Rich Girl September 25, 2012. actor Malcolm-Jamal Warner contributed a poetry-slam-style
