Desmond Tan is no stranger to showing skin on screen. The hunky actor famously bared his bum in Derek, and will once again be shedding his clothes for season 2, now available on meWATCH. With one of the most ab-tastic bods on Stars Avenue, you would think going shirtless would be a walk in the park for the 34-year-old. But it turns out that Desmond isn't always shirtless shoot-ready and maintaining his six pack for his role as maniacal serial killer Derek Ho was sheer torture. In fact, just thinking about it brought back so many “bad memories”, Desmond almost didn’t want to talk about it. Seriously?!
