(WHAS11) -- A YouTube video of a marriage proposal in Portland, Oregon has quickly turned viral.
Issac Lamb, the groom to be, asked his girlfriend Amy Frankel to meet him at his parents' house for dinner.
Issac's brother put Amy in the back of a car and as it drove away, a group of Issac's friends lip synched Bruno Mars' "Marry Me."
Once the song was over, Issac emerged from the crowd to pop the question.
