"Totally baseless and without merit" is how an attorney for Sugarland describes a lawsuit filed last month by a former member of the band. Kristen Hall, who co-founded Sugarland in 2003, is suing her former partners for more than $1.5 million.

Hall, pictured left with Sugarland's Jennifer Nettles and Kristian Bush, says she was promised a share in the band's profits and losses after her departure in 2005. She left the group to concentrate on her songwriting. It was the manner of her exit that Sugarland's attorney says is a big factor in the case.

"Among other factual inaccuracies suggested in the complaint, it is indisputable that Ms. Hall left the group voluntarily and on her own accord," writes Gary Gilbert in an official response to Hall's lawsuit. "We are absolutely confident that this matter will be resolved in favor of Jennifer and Kristian."

Hall wrote or co-wrote every song on Sugarland's debut album, 'Twice the Speed of Life.' She left the band before work began on their second album.
