Mexican singer made a mistake singing the National Anthem; Blue Demon Jr.'s reaction goes viral.

USA—Once again, Mexican singer Deyra Barrera was included in a major sporting event. However, unlike her participation in the posthumous tributes to Fernando Valenzuela , the "Bull of Etchohuaquila," this time her performance drew criticism.

But the curious thing is that not only was she “attacked” by the fans and the general public, Blue Demon Jr. also reacted to the mistake he made during an event prior to WWE Worlds Collide 2025 .

WWE has decided to involve the national flags of Mexico and the United States in a pre- Worlds Collide 2025 event, which will take place this Saturday, June 7, with Lucha Libre Triple A.

But before the fights, Mexican singer Deyra Barrera entered the ring to sing the National Anthem , however, she made a mistake in her interpretation and therefore experienced an awkward moment.

In a video circulating on social media, you can see how the singer, dressed in a spectacular mariachi outfit , performed in the middle of a ring where figures such as Triple H, Shawn Michaels, Blue Demon Jr. , Pagano and Marisela Peña were standing.

But when singing the national anthem , he unfortunately made a mistake in the lyrics and tonality of this national flag.
