Duc Thinh offends his friend Cat Phuong to defend his wife Thanh Thuy 

Even though the argument between director Duc Thinh and his former close friend, artist Cat Phuong, was over, echoes of their disagreement were evident in newspaper interviews printed after the fact.

The argument started after Cat Phuong, singer Phan Dinh Tung's partner on Just the Two of Us 2013, answered a question newspaper interview, and seemed to imply that she was a bad teammate for the competition.

“I believe that I would have been the winner if the judge panel had been fair,” she commented.

In response, Duc Thinh, in attempt to defense his wife, actress Thanh Thuy, who won the first prize together with her partner singer Duong Trieu Vu, made offensive comments about Cat Phuong on Facebook.

“Phuong is just out for herself, but I'm not bothered by that because she has always been superficial," Thinh commented.

Phuong told newspapers afterwards that the comment made her cry and almost collapse. She recounted their former close friendship.

Even though Duc Thinh and Cat Phuong have met to renew their friendship and Thinh has removed his Facebook comments, it's been reported that their friendship has never fully recovered.

The argument between singer My Le and musician Luu Thien Huong also seems to have left permanent damage on a celebrity relationship.

After judge Luu Thien Huong commented on the performance of the couple My Le and Khuong Ngoc, also on Just the Two of Us 2013, My Le directly responded onstage that she thought the decision unfair. The disagreement went beyond the show and spilled into the print media.

Many thought it was the pressure to defend their reputations in front of the audience compelled them to make a public reconciliation during the next show.

Actor Hoa Hiep gave an icy farewell to the judge panel after comments by director and judge, Le Hoang, at the Dancing with the Stars 2013, saying, "Thanks so much to the judges for giving us such a low score. It allows us to stop here. I think I should end my part in the competition, as I am not satisfied with the way the judges treat us. It's very stressful," Hiep said.

The actor went on to make comments to newspapers, saying that Le Hoang was an idiot and he did not admire any of the judges, including Khanh Thi, Le Hoang and Tran Ly Ly.

The relationship between singer Dam Vinh Hung and singer Thanh Lam was also put under extreme stress after Thanh Lam cast doubt about her role performance with Dam Vinh Hung and Ho Ngoc Ha in the programme Voice Vietnam.

Dam Vinh Hung was so angered as to say that Thanh Lam, who had been his close friend, was like a “toxic ant” and that he would not even look at Thanh Lam anymore.

Ho Ngoc Ha aimed insulting words at her son on Facebook in order to target Thanh Lam.

Several members of the public assessed that such incidents have helped them understand more about Vietnamese showbiz.

Singer Phuong Thanh said, “People should not exchange friendship for fame on reality TV.”
