Miranda Lambert is currently completing her third album and expects to release it in September, according to Billboard. She's recording the album in Nashville with Frank Liddell and Mike Wrucke, who also worked on her most recent album, 2007's Crazy Ex-Girlfriend. Lambert says she hopes to complete the project before launching her summer tour opening for Kenny Chesney. She indicated that Blake Shelton, her boyfriend, may appear as a special guest on the album if they can find the right song.
