A bad romance could cost Lady Gaga millions. The pop star has been slapped with a $30 million lawsuit from a former boyfriend who claims the singer stiffed him after he dumped her.

Songwriter and aspiring music mogul Rob Fusari credits himself with making “Gaga” a buzzword.
Fusari — who helped pen the Destiny’s Child hit “Bootylicious” — says he molded Stefani Germanotta from a “young Italian girl guidette” into one of the dynamic forces in music today, even giving her her bizarre stage name. The pair worked together seven days a week for more than three years and co-wrote Gaga’s hits “Beautiful, Dirty, Rich” and “Paparazzi.”

However, Rob argues that ever since he ended his romantic relationship with Gaga in 2007, the “scorned woman” has worked tirelessly to cut him out of a business deal that entitled him to 20 percent of her royalties and merchandising rights.
