Our thoughts are with Bruno Mars. His beloved mother, Bernadette Hernandez, has died.

A source close to the family and to Mars' label, Atlantic Records, told The Associated Press that Hernandez suffered a brain aneurysm and passed away yesterday (June 1). It was reported yesterday that Hernandez suffered a severe heart attack on May 31.

Hernandez was 55 years old. She passed away at Honolulu Queens hospital in Honolulu, Hawaii.

Mars was spotted at LAX on May 31 (see photo above), though it is unclear if he was on his way to be at his mom's side. Hernandez was immensely important to Mars, who often and openly expressed his adoration for her. You can see examples of that -- including a promise to quit smoking -- in the tweets below from Mother's Day.

We wish the best for Mars and his family during this difficult time.
