Let the countdown to Stormzy's debut album begin.

After taking some time out of the limelight towards the end of 2016, speculation has mounted over when we can expect Stormzy's first album to drop and thanks to a series of mysterious billboards in London, we might have our answer.

As reported by FACT, two billboards appeared in Hammersmith and Shoreditch overnight with Stormzy's #Merky logo in the corner alongside a quote, a potential album title in #GSAP and a possible release date of "24.02".

Details on the album are still pretty scarce but this is the closest thing to 'news' on the album we've seen in months.

What does #GSAP stand for? Let the speculation begin.
