Government officials in Bruno Mars' native Hawaii have honoured the singer with his own day for a second time.

In 2010, the Treasure hitmaker returned to his home state for the first time after hitting it big, and Hawaiian officials announced 19 December would be Bruno Mars Day, and now, four years later, locals celebrated again on 21 April (14), as Mars capped off a three-night, sold-out gig in Honolulu.

Unlike the first honour, Monday's celebration is a one-off occasion, and not meant to be celebrated every year, like singer's December festivities.

The 2014 proclamation reads: "Bruno Mars’ talent for combining catchy pop melodies, hip-hop beats and feel-good lyrics has helped him emerge as one of Hawaii's most popular artists.

"We ask all citizens of the Aloha State to join us in celebrating the achievements of Bruno Mars in representing Hawaii well in America and around the world with his exceptional talent and performances."
