So, when you project something onto the side of the building, you can be sure that it will get some eyeballs.

Hello from the other side?

A few days ago, a mysterious projection of the number '30' adorned the Twin Towers, and it captured the attention of Malaysians.

Here's what it looks like:

To make things even more mysterious, the '30' projection was not only spotted in Malaysia, but it was plastered on some of the world's most iconic landmarks such as the Louvre in Paris, the Empire State Building in New York and the Colosseum in Rome:

And music fans have a good reason to believe that Grammy Award-winning singer Adele could be the mastermind behind the projections.

New music incoming?

According to a report by Creative Bloq, the projections of the number '30' that appeared all around the world feature two font styles: a thinner one that was used on Adele's '21' music album cover, and another layered, more stylistic one similiar to her '25' music album:

On top of that, Adele has always named her music albums after the age she started it at (her previous albums were titled '19', '21' and '25'), and seeing she just turned 33 this year, '30' could very well be the title of her new album.

To further add fuel to the fire, Billboard reported that a radio host accidentally let slip earlier this week that a new Adele album is on the way in a now-deleted Tweet which said, "New Adele. This week.”

And if that's not enough proof for you, even some of the world's biggest musicians such as Ed Sheeran and Nicki Minaj have confirmed collaborations with Adele on her upcoming new album.

This tweet by a Twitter user named @gianniborrelli could be the nail in the coffin:

Spoke to the gent running the projector who said he was “contracted by Sony to run it” and didn’t know what it was for. No way this isn’t for Adele’s next album ?

Back in 2016, the "Rolling In The Deep" singer signed a deal worth USD130 million (RM542 million) with Sony Records, making it the most expensive record deal signed by a British artiste ever.

Unless the 32-year-old Neelofa decides to turn back the clock and throw another 30th birthday party by projecting the number '30' on the Petronas Twin Towers, it's looking more likely that Adele will be dropping her new album soon.

Are you guys excited?
