The husband of Jenni Rivera is suing the owners of the plane that crashed in northern Mexico in December 2012, killing the Mexican-American pop star and six others.
City News Service says former Los Angeles Dodgers pitcher Esteban Loaiza filed the wrongful death case Friday in Los Angeles.
Among other things, the lawsuit claims that the pilots weren't licensed to fly paying passengers.
Rivera sold more than 15 million records.
The 43-year-old superstar filed for divorce from Loaiza two months before the crash, but the lawsuit says he continued to receive financial benefits from her.
A call to Mark Velasquez, a San Diego attorney representing plane owner Starwood Management, wasn't immediately returned.
