Her third solo album, My Turn (2009), projects a new, sexually-charged image which she adopted while living in the United States and performing frequently on Thúy Nga Productions' variety show, Paris by Night.

The show gave her an opportunity to perform "Ngày mai (Vũ điệu cồng chiêng)", the song which brought her success and later became one of her signature hits.

[2] Tiên made her film debut in Già gân, mỹ nhân và găng tơ (2015), and has signed numerous endorsement deals.

[6][non-primary source needed] Tiên was four when her family discovered her singing ability and allowed her to join the performing group of the Children's House of Ho Chi Minh City.

[9][1] After she was one of the show's twelve finalists, Tiên supported musician Thế Hiến on his 2002 nationwide Đợi chờ trong cơn mưa concert tour, which marked her debut as an adult singer.

[15][16] Tiên made her acting debut when she was the first actress to portray doctor Đặng Thùy Trâm for a segment aired on the VTV3 talk show Người đương thời.

[13][17] She later participated in Tiếng hát truyền hình toàn quốc giải Sao Mai, her third singing competition; this surprised many since Tiên was an established performer at the time.

[19] One of eighteen Southern finalists, Tiên sang Đỗ Bảo's "Bài hát cho em" on 19 November 2005, live show but lost.

[26][27][28] Quốc Bảo, Phương Uyên and other songwriters were enlisted for her second album, Tóc Tiên thiếu nữ, which was scheduled for release in June.

"[31] Early in 2011, Tiên rushed to finish a collaborative album with her long-time friend, singer Wanbi Tuấn Anh, before moving with her family to Los Angeles in March.

[34][35] By 2016, Tiên had appeared on more than forty episodes of Thúy Nga's direct-to-video variety series Paris by Night, starting with her performance of "Tóc mây" on the 96th installment in June 2009.

[37] In September 2010, Tiên made a cameo appearance on Wanbi Tuấn Anh's music video for "Bắt sóng cảm xúc" and was featured on the song's R&B remix.

[38] Her third solo studio album My Turn was released in August 2011, and includes contributions from Dương Khắc Linh, Nguyễn Hải Phong, Thanh Bùi and others.

[42][43] In July 2013, Tiên reported that she had transferred to California State University, Long Beach and changed her major to communication studies to balance her education and career; however, she eventually dropped out.

[48] TeamV—which consists of Tiên and producers Touliver and Long Halo—would go against other notable acts such as Sơn Tùng M-TP and Đông Nhi, to create the best remix work on the program.

[60][61] In December 2015, Tiên starred in her first comedy film Già gân, mỹ nhân và găng tơ as Quỳnh Cherry, a DJ on the run from a group of gangsters.

[74][75][76] These two singles were from her then-upcoming extended play T.[76] The album's lead track "The Beat of Celebration" featuring BigDaddy, JustaTee and Touliver, brought her the Silver Music Video and Most Effective Performer awards from Bài hát tôi yêu.

[77] In March, she recorded "Một con đường hai ngã rẽ" for the soundtrack of the comedy film Taxi, em tên gì?.

[82][83][84] Dutch producer Afrojack and rap artist Suboi joined one of them, "Tâm điểm ánh nhìn (All Eyes on Us)", the trio's song for Budweiser released in December.

[87] Tiên also released a few other singles throughout the year, including: "Em không là duy nhất" in February, which was successful, "Walk Away" in May, and "Hôm nay tôi cô đơn quá", a collaboration with Rhymastic, in August.

[54][94][95] "Hôm nay tôi cô đơn quá" later received both Single and Song of the Year nominations at the Làn Sóng Xanh and Dedication Music Awards, respectively.

[23][29] Her follow-up Chuyện tình vượt thời gian with Wanbi Tuấn Anh has the two performing and covering a handful of love songs, in genres such as blues jazz and alternative rock.

[99][100][98] Tiên later said that the hair cut was one of the "turning points" that helped her discover herself, while the image change was a "natural" progression, a result of her time working in the States.

[49][102] The trio's successful collaboration, "Ngày mai (Vũ điệu cồng chiêng)", was made famous by the chorus that infused house music with the use of drum and percussion, all creating a notable gong-like sound.
