On the evening of May 26, Jack announced that he had filed a complaint against actress Thien An for spreading false rumors, seriously affecting the male singer's personal image. This move attracted attention from the online community, evoking the couple's 4-year love scandal.
The relationship between Jack and Thien An started in 2019, when the 9x hot girl was invited to appear in the MV "Song gio". After that, the beauty from Binh Duong became Jack's "muse", continuously appearing in the MVs "Bac Dinh", "Sao em bat don", "Hoa bat col".
Thien An impressed with the image of a beautiful country girl, charming, having difficult circumstances..., being loved and protected by the male lead ( jack). The series of MVs won the sympathy of the audience, making fans actively "ship" the couple's love.

The MV series "Sure of progress" and "Sure of wind" helped Jack and K-ICM quickly become a phenomenon on social networks at that time.
Music products with the collaboration of Jack and Thien An also brought good results, becoming a phenomenon on social networks. Of which, the MV "Bac Thanh" reached 100 million views in just 1 month and 17 days, "Song gio" only took 25 days to achieve the same result.
Up to now, "Song gio" has 453 million views, "Bac dinh" with 420 million views, are the 2 most watched MVs in Jack's career. Other MVs with Thien An's participation also brought positive results such as "Sao em bat don" with 58 million views, "Hoa bat trang" with 52 million views.
It is undeniable that Thien An has had the time to accompany Jack during the golden period of his career.
However, this relationship quickly fades away, becoming the source of a series of storms for both of them.
In early August 2021, a social media account spoke up to accuse Jack of catching fish with both hands, dating at the same time as him and Thien An. Not long after, Thien An herself revealed that she had a child with Jack, and provided her with a birth certificate at the hospital.
Amidst a series of undeniable evidences, Jack posted admitting to having a child with Thien An but confirmed that the two no longer have a relationship. The male singer faced a major crisis in his career, was boycotted by the audience, and eliminated from the reality show.

At that time, Jack announced that he would take care of the joint child with Thien An. However, at the end of 2022, Thien An spoke up to reveal that her ex-boyfriend had stopped giving her daughter child support since March 2022, and also did not repay the debt to help her family with the reported 2 billion VND.
Despite public criticism, Jack continued to remain silent about the incident. The male singer still sang and released new music products but did not mention Thien An and her daughter.
As for Thien An, she started her artistic career again to earn money to cover her living expenses. The beauty appeared in a number of films such as "Upper-class Schemes", "Linh Luc: Quy Nhap Trang"...
In January 2025, she unexpectedly shared about her time with her ex-boyfriend, revealing that she had phaled the pregnancy twice in 2020 to "not ruining his career". The third time, she decided to keep the child (little Sol) and keep the information a secret from the family. Thien An affirmed that she only wanted to live in peace and continue working.
Thinking that everything would go on like that when Jack and Thien An both pursued their own careers, the complaint from Jack to his ex-girlfriend once again caused a stir in public opinion.
Currently, Thien An has not commented on Jack's new move. However, the online community discovered that she had deleted a series of previous posts revealing that she was pregnant 3 times with her ex-boyfriend.
