Local actor and comedian Hossan Leong worried fans for a moment when he posted a photo of himself on Instagram -- looking significantly plumper.
Some questioned if he had mumps. Comments on his Instagram include:
"Oh my god!!"
"You look so fat, no offence."
Local singer Roy Loi also chimed in: "oy ! U owe ppl money kena whack ah ? Hahaha"
His 'fat' look was actually a video for MediShield Life by MOH Singapore, where he plays both a round-faced father and a sullen-looking son.
He wrote: "Please remember to log in to www.medishieldlife.sg with your singpass. Only 1 member in each household need to do this.
"Any member of the family can do it. You need to do this by 6th June 2015. #MedishieldLife"
The campaign involved Hossan Leong getting plastered with a fat suit by prosthetics flown in from the US.
