Now, they still maintain a close colleague relationship, always chatting and happy every time they meet.
In April 2023, Bao Anh suddenly announced information about her 1-year-old daughter. The information surprised the audience because before that, the female singer had never revealed anything about her pregnancy and childbirth.

It was also at this music show that Toc Tien and Hoang Touliver met each other. In 2019, the couple publicly dated.
In early 2020, Toc Tien and her significant other got married but did not reveal their wedding photos and kept their private life private.
After getting married, Toc Tien often goes into the kitchen and learns to make all kinds of dishes. Toc Tien and her husband do not have children but enjoy married life with trips, working out together, cooking, dating...
Toc Tien said she feels lucky to have a husband who works in the same industry. Hoang Touliver is a solid supporter of the singer's career, understanding and supporting each other on the path of artistic activities.
