This is the heartwarming moment a boyfriend proposed to his partner in the middle of a Bruno Mars concert in the Philippines.

The Filipino-American singer was singing his hit song 'Marry You' to the crowd at the Philippine Arena in Bulacan, around 30 kilometres north of Manila, when the boyfriend pulled out an engagement ring for his lover on June 25.

Heartwarming footage shows the emotional bride-to-be crying tears of joy as she accepted the proposal, to the delight of cheering onlookers. The couple then shared a kiss and a hug as the audience applauded them.

The Grammy-winning singer-songwriter was in the Philippines for a two-day concert over the weekend, playing to a sold-out first night on Saturday. He last visited the Philippines for his 24K Magic World Tour back in 2018.
