Justin Bieber backed American gymnast Simone Biles, who caused a scandal at the Olympics

One of the most high-profile events at the Tokyo Olympics was the refusal of 24-year-old Simone Biles, the leader of the U.S. women’s gymnastics team, to take further part in the competition. The athlete said she put her mental health first and would not compete for medals. On the Web, her action became a hot topic of discussion: some people support Simone, while others call her selfish.

Many celebrities have publicly stood up for Biles, one of the last to speak out was 27-year-old Justin Bieber. On his Instagram page, the performer wrote that no one will ever understand the pressure Simone faces and what she is going through.
