Born in Jianshi Township, Taiwan on November 17, 1988, Joanne Tseng (曾之喬) is an actress, singer and TV host of Atayal (indigenious Taiwanese tribe) descent.

Tseng graduated with a Drama & Theater degree at National Taiwan University of Arts, and is able to play piano, flute and violin.

She debuted in the music industry in 2003, along with Esther Liu, in the group Sweety, until 2007, with Liu going off to study in Paris and Tseng focusing on her solo career, which marked the beginning of an indefinite hiatus for the duo.

Tseng would go on to debut as an actress both in Taiwan and mainland China, with her first acting role in 2004, in the Taiwanese drama 紫禁之巔 (Top on the Forbidden City) as the lead actress. Aside from acting, Tseng provided songs for dramas she starred in, as well as others, but did not make a return to music until the release of the EP 亮了 (Light Up) in 2017, which officially marked her re-debut as a singer.

In January of 2020, Tseng announced her marriage to former Fahrenheit boy band member Calvin Chen on her Instagram, though the pair had been in a relationship for nearly a decade prior to the wedding announcement.

Joanne is signed to HIM International Music.
