Little Big Town’s Philip Sweet has announced that he and his wife Rebecca are expecting their first child together. The couple married in March. “We’re crazy excited,” Sweet said in a phone message on the band’s Web site. “We just don’t know what to do. It’s like something is on the LBT bus.” Bandmate Kimberly Rhoads is also expecting her first child this summer, following her marriage last year. The other band members, Jimi Westbrook and Karen Fairchild, were also married in 2006.
