The singer will release 'Can't Say No' as his debut single on April 16 through EMI after being discovered on YouTube.
The video, which was shot in East London and directed by Rohan Blair-Mangat, sees Maynard clubbing with a number of girls.
Earlier this year, Maynard was named the winner of MTV's Brand New for 2012 competition and will receive ongoing priority endorsement throughout the year from the network.
He won the competition with more than 50% of the vote, beating rivals such as chart-topper Lana Del Rey and newcomer King Charles.
