Dennis Chew

Chew studied at the former Pearl's Hill Primary School and Tuan Mong High School (predecessor of Ngee Ann Secondary School). At 13, Chew performed in the musical and children's television programme 《成语50》(Chinese Idioms 50). At 14, he was talent scouted for a commercial for Yakult. He was part of the first batch of students in the teen acting classes organised by the Singapore Broadcasting Corporation during the late 1980s. In 1991, he played a substantial role in the TV drama The Future is Mine (锦绣前程).

After serving his National Service, Chew went on to Shatec to get a Diploma in Hotel Management as he realised during NS that it is important to further his studies. Chew became a Chinese teacher in Yumin Primary School and Raffles Girls' Primary School after completing his education. At the same time, he also worked as a part-time DJ at local radio station YES 933. A few years later, he signed on as a full-time DJ with YES 933.

In Jan 2005, Chew released a music album, containing nine original songs.

Chew's big break in television came in 2009 when he portrayed Aunty Lucy in the variety show Paris and Milan (女王本色), which also starred Patricia Mok, Michelle Tay and Ben Yeo. His performance was extremely well received, earning him popularity which led to his first ever win (Top 10 Most Popular Male Artistes Award) at the annual Star Awards in 2010. The character's catchphrase "Aiyoh, so embarrassing!" and the swooshing of his head to the right was popular with audiences. "Aunty Lucy" was also featured in films like Aunty Lucy Slam Dunk (Auntie Lucy 也灌篮) (2009), It's a Great, Great World (大世界) (2011) and Dance Dance Dragon (龙众舞) (2012), and the game show We Are Singaporeans (season 1 - 2011) as a guest. Chew later stated in an interview that the success of Aunty Lucy was a major turning point in his career, and the endorsement deals it brought helped him clear debts which he had incurred from an unsuccessful business venture.

While juggling DJ duties, Chew also hosts many different programmes ranging from roadshows, variety programmes and game shows, and starred in several television series. He had also participated in several local productions and films. These include the 881 The Musical, in which he played the role of an evil artiste manager. In February 2013, Chew finalised his plans to move over to Love 97.2FM in mid-March as DJ, after hosting at YES 93.3FM for 20 years.

In 2019, Chew appeared in an advertisement by e-payments website epaysg.com, where he portrayed characters such as a woman in a tudung and a man with visibly darker skin. Broadcaster Mediacorp, through its celebrity management wing, later apologized for the controversial ad and the epaysg.com website has also removed it.
