The singer will release 'Last Time' as his third single on March 11, ahead of his debut album Electronic Earth a week later.
A clip of the accompanying music video features the star as a young boy hanging out with a blue alien, while other scenes see flying pigs, cities towering from the ground and an alien riding a dinosaur.
'Last Time' was written and produced by Labrinth at his home studio in Wood Green, London. He recently described himself as a "musical geek".
Labrinth will start his first headline tour of the UK on February 23 at Birmingham's HMV Institute. The string of shows will conclude at Brighton's Concorde on March 8.
