They tie at 27 tens, meanwhile the second season winning couple Vũ Thu Minh & Lachezar Todorov only gets 15 ones. For the best average score from judges to all contestants, Ngô Thanh Vân & Tihomir Gavrilov currently come first on top of the all-time board being 37.5/40 for their dances, followed by Vũ Thu Minh & Lachezar Todorov (36.7/40), Cao Thị Đoan Trang & Evgeni Popov (36.5/40).

Highest and lowest scoring performances

 * The routines were not applied for scoring. During the season 1 finale, Đoan Trang & Evgeni chose it as their favorite and got scored. So did Ngô Thanh Vân & Tihomir.

Unfair scores
In season 2 the case of Anh Khoa and Iva, all four judges gathered for quick break for discussion about giving scores unlike independently as usual.

And to all seasons, judges are harshly criticized for giving generous scores very sentimentally based upon the case that contestants or partners' sickness, family's bad luck, not so serious injury and so on. That discriminates much against participants who have devoted their really faithful performances based upon hardworking rehearsal and upon creativity. Season 1 winner Ngô Thanh Vân showed disagreement that she would quit because of scoring unfairness. Season 2 finalist Thủy Tiên expressed her feeling of wrong critics and bad scores.

Phone voting/Textgate
In June 2011, the show hit the headlines when viewers were able to register telephone votes for a couple that effectively they could not save from the dance off irrespective of how many public votes were cast in their favour. Some voters claimed that they couldn't send messages voting for Anh Khoa & Iva eliminated the same week during textgate open, when received confirmatory text "Vui lòng nhắn tin bình chọn sau khi các thí sinh đã tham gia xong phần thi của mình. Xin chân thành cảm ơn" (literally: "Text after all performances done. Thank you for voting"). It is not clear if the "Thank you for voting" messages were incorrectly assigned, as if the replies were incorrectly assigned, votes would have been counted for the correct contestant despite the voters receiving the wrong "thank you" messages. No message responded even 7 hours after texting was affirmed as well.

All involved including the broadcaster, producers and textgate owner informed no errors during week 9 (June 26) in public press. They also revealed the out of phase of the text-gate with live audience which meant people could only text formally from 30 seconds up to a minute in normal mode after the announcement of hosts and clearly voting could be continued during short time when the gate was deemed closed.

Cast members
Many celebrity are claimed the involving in the show like Phan Anh, Ngọc Tình and Vĩnh Thụy of season 2 step by step replacing. Moreover, Vĩnh Thụy reservedly or unreservedly quit regarding on the accusation of smuggling from Australia to Vietnam by air and the lawsuit filed against him.

Timing violation
Every performance should be performed in 1.5 minutes according to standard practices in almost all versions Dancing with the Stars and in international competitions. On June 6, 2011 the length of Thu Minh's performance was deemed the longest and the shortest performance was that of Đại Nghĩa with only 1 minute 40 seconds. Once again on June 26 and in the finale of season 2(July 3), Thu Minh & Lacho had additional performances.

Striptease
Tendency of undressing on stage was up gradually, beginning in the first week and accumulating in the finale. It is more focused on the "tease" in "striptease" than the "strip". These actions are considered over-sexy, seductive and influence the culture in a bad manner.

Winner crowning
There was much discussion in the communication industry about the real season two winner because there was confusion over the crowning. Initially, Đoan Trang revealed the runner-up, thus the other was the winner. Trang announced 79 scored by the runner-up. Moments that turned Thủy Tiên (who obviously scored 77) to the edge of glory and turned Thu Minh (who truly scored 79 out of possible 80) slightly blue was quickly stopped with the real name "Thủy Tiên", leading everyone got shocked. Under too much pressure, producers finally agreed to make a press conference in free will to give info about textgate in order to clarify everything. Mistakes of mis-crowning was caused by result paper as interpreted.

Mimicking
On June 5, Thu Minh wowed the judging panel with her exotic dance concept that brought her two 10s for Samba. Later, it was revealed that the choreography and wardrobe she wore looked amazingly similar to those of Max Kozhevnikov and Yulia Zagoruychenko in the World Super Stars Dance Festival in 2006. In sudden press reports earlier in the week, two main judges Khánh Thi and Chí Anh stated "mimicking is actually self mastering, is the creativity of Thu Minh and Lachezar". Producers tried to help Thu Minh, claiming it was not Thu Minh's fault, that the wardrobe was made from our set of designers' ideas and gave no comment about the choreography.

Producers' rigging
Reportedly by various newspaper, producers rigged the show. Participants were eliminated as audience thought in an elimination order written in the screenplay. Lương Hoàng Anh, who was Huy Khánh's ex-wife, used Facebook note for raising a tension with the producers after he was out of the race. She also reported Khánh had said to their kid to watch his elimination on Bước nhảy hoàn vũ on Sunday night prior to his elimination actually occurred. Producers denied these claims as baseless, stating that there was officially a company collecting and analyzing messages, and the results were not to be revealed by producers alone without VTV's permission.
