Gurmit is married to Melissa, a Cantonese Chinese. He has a fifteen-year-old[when?] daughter, Gabrielle (Gabbi Wenyi Ayane Virk); and a seven-year-old[when?] son, Elliot. His son Elliot has enrolled into SST in 2013. Gurmit is an alumnus of National Police Cadet Corps, Singapore and held the rank of Cadet Inspector. He drives a Grigio Telesto Lamborghini Gallardo.
Making his debut in the variety show Live On 5, he then became the host and lead actor of the comedy Gurmit's World. The second season of Gurmit's World, in which Gurmit portrayed his 'relatives' in a series of skits (unlike the first season where he played a wide assortment of mostly non-recurring characters), featured the first appearance of a character named Phua Chu Kang. The Singlish-based spin-off sitcom Phua Chu Kang Pte Ltd in 1996 made Gurmit a popular icon in the recent years, not only in Singapore, but also in neighbouring countries (especially culturally similar Malaysia). This factor led him to be the host in the Singapore Idol variety show. In the past few years,[when?] Gurmit has also won the Top 10 Most Popular Male Artistes at the Star Awards.
