Watch This Guy Sing Adele's 'Hello' in His Underwear

'Hello from the other side': One man got in his underwear and sang Adele's hit while on holiday in Singapore.

A parody of Adele’s “Hello” was recorded in Singapore and is climbing the video charts, as many viewers believe the rendition was produced for the city's tourism board.

The music video was posted on YouTube in November by its creator, American fitness model, personal trainer, and author of The List, Bryan Hawn.

People began paying attention to the video once Kenneth Tan, who is from Singapore, posted the clip to his Facebook page, jokingly writing that it was "produced for the Singapore Tourism Board.”

The tourism board for the country is known for making left-of-center tourism promotional videos like one they produced on their locals -- cats.  

Hawn's video has also been shared over 9,000 times from Tan’s account., More than 4,000 comments have flooded the post. 

Hawn says the ironic part is the music video is neither a tribute to Singapore nor the singer. The country just happened to be one of his ports of call on a recent cruise.
