Bruno Mars is mourning the sudden loss of his mother, Bernadette Hernandez. The 27 year-old singer's mother suffered a brain aneurysm and passed away at the Queens Medical Center in Honolulu, Hawaii, unexpectedly on Saturday, June 1st. She was only 55 years-old. Hernandez migrated to the United States from the Philippines and soon found work as hula dancer and singer. She was responsible for nurturing Mars' talent at a young age. Hernandez gave birth to six children including two boys and four girls. Mars' brother is his drummer while his four sisters have formed their own music group. Mars is scheduled to launch a tour later this month. There's no word yet on if his mother's death will impact the tour.
