Miranda Lambert hosted her biggest fan club party to date Sunday morning (June 12), expanding the annual celebration from 300 to 500 people. Held at the Nashville Palace, a bar and grill located right outside the city, fans enjoyed burgers, barbecue and beer pong prior to the singer's performance. Once onstage, Lambert performed "Gunpowder & Lead" and a few songs from her 2009 album Revolution including "White Liar," "Time to Get a Gun," "The House That Built Me" and her most recent No.1 hit, "Heart Like Mine." At one point, she looked down at the sparkling boots she was wearing and said, "Thanks for these boots. 'White Liar' bought these. These are my No. 1 boots!" She later introduced the crowd to Ashley Monroe and Angaleena Presley, members of her newly-formed trio, the Pistol Annies. Together they performed a few songs including the group's debut single, "Hell on Heels." Lambert also performed as part of the trio that evening at LP Field as part of CMA Music Festival's closing night. They joined the lineup of Taylor Swift, Blake Shelton, Darius Rucker, The Band Perry and the JaneDear Girls. View photos from Miranda Lambert's fan club party.
