Watch: Was Lady Gaga's Rio concert really attended by 2.1m people?

The news article examines a claim made by Rio de Janeiro officials that Lady Gaga's concert on Copacabana beach was attended by 2.1 million people. BBC Verify, a fact-checking service, investigates the validity of this statement. The article notes that if true, this would make the concert the largest ever held in Rio. However, it points out that the figure seems questionable, as the city's population is only around 6.3 million. The article also highlights that the area where the concert took place has a capacity of around 700,000 people. Furthermore, the article mentions that the organizers have not provided any evidence to support the 2.1 million claim. It concludes that while the concert was undoubtedly a major event, the attendance figure reported by Rio officials appears to be exaggerated and unsupported by reliable data.
