The singer and producer will perform at London's Pulse nightclub on March 7.
The gig, which fans can win tickets to via Facebook, is to promote Wrigley's 5 Gum's launch of its new Evolution flavour.
The concert, hosted by Kiss FM DJs Ricky & Melvin, comes the day after his sold-out show at the capital's Koko club, giving fans a rare chance to catch him live in an intimate set.
Singer-songwriter Yasmin and Pepstar are the first acts announced to support the show, with more artists expected to be confirmed in the coming weeks.
The star recently released a teaser of the music video for his new single 'Last Time', which is out on March 11. His debut album Electronic Earth follows a week later.
