I've never seen Ho Le Thu's daughter but I know she has a kid with her first husband, a musician. The daughter is named Phi Anh and is about 18 years old. The singer shared this picture below with her daughter with the caption "Sunday o nha , hai me con go out , eating yogurt . happy Sunday Mom n Daughter. lau lam roi moi co 1 weekend o nha voi con. I love this moment." It is nice to know she got some mom and daughter time. It is rare that singers get to stay home on a Sunday (especially those that are popular for shows like Ho Le Thu). Phi Anh looks so much like her mom. You can see it in the smile and eyes.
Here is another picture of Phi Anh from Ho Le Thu's Facebook.
