Beyoncé has reportedly “bowed down” to fellow music icon Mariah Carey — vacating her luxurious £25,000-a-night penthouse at London’s Corinthia Hotel to allow the diva to move in ahead of her return to the UK stage.

Queen Bey, 43, had been staying at the hotel while performing at Tottenham Hotspur Stadium but moved out when Mariah, 56, arrived to headline Capital’s Summertime Ball at Wembley Stadium.

“Beyoncé packed up so Mariah could take over her suites. It was like Beyoncé was bowing down to another music queen,” a source shared.

Mariah’s signature diva behavior also extended backstage, where she renamed her dressing room “Mimi’s World” and removed all Capital FM branding.

In contrast, co-headliner Will Smith was described as “chilled,” reportedly grabbing food in catering like a regular guest.

Mariah closed the show with hits like “Fantasy,” “Emotions,” and “Hero,” marking her first UK performance in six years.
