Poor Bruno Mars! His beloved mother is in the hospital following a severe heart attack.

Mars' momma, Bernadette Hernandez, was rushed to a hospital in Honolulu, Hawaii. Hernandez is said to be in critical condition.

Mars' and Hernandez's family friend, Anita Sojot, informed Star (via Radar Online) that her loved ones were gathering to be at her side.

Mars has made no secret of his adoration for his mother throughout his career. One of Mars' signature songs is actually 'I Love You Mom,' initially recorded when he was just four years old. We bet he's singing that tune with extra feeling now.

Our thoughts are with Mars and his family during this difficult time. Here's wishing Hernandez a speedy recovery!
