Nicholas Teo, born November 29, 1981, also known as Nicholas Zhang and Zhang Dong Liang, is a Chinese-Malaysian actor and singer signed under Play Music. Before returning to Malaysia, Nicholas was studying in Taiwan, where he won the Best Singer in a competition among all the Taiwan Universities. Thereafter, he was approached and asked if he would sign up with a company as a back-up singer (backing vocalist, to harmonize with the lead vocalist), which Nicholas subsequently ignored. He returned to Malaysia without finishing his studies and participated in the singing competition "2002 Astro Talent Quest". Nicholas won first place with the song "Sunset" (Huang Hun), originally sung by Zhou Chuan Xiong. This led to Nicholas signing a contract in Taiwan with Music Street in 2003. On June 18, 2004 he released his first album "1st Choice Nicholas." Music Street eventually merged with Warner Music, and it should be noted that Play Music is a record label subsidiary of Singaporean company Musicstreet Pte Ltd. In 2006, Nicholas received the 2006 Hito Newcomer Award in Taiwan. He also successfully completed his From Now On Concert Tour covering stops in Malaysia, Singapore, and Indonesia within the first half-year of 2008.

Nicholas stars as pop idol He Qun in the 2006 Taiwanese drama, Smiling Pasta (Wei Xiao Pasta), and is also casted as Sun Wu Di in the 2008 drama Invincible Shan Bao Mei.
