Bernadette Hernandez -- mother of Bruno Mars -- died unexpectedly Saturday at the age of 55.
Hernandez suffered a brain aneurysm. She passed away at the Queens Medical Center in Honolulu, Hawaii.
Hernandez was a hula dancer and singer who immigrated from the Philippines and nurtured Mars' musical talents from a very young age.
Mars was set to kick off a tour in the U.S. later this month. No word on whether the death will affect the concert schedule.
