Mariah Carey's backstage demands at Capital's Summertime Ball at Wembley Stadium on Sunday have been unveiled as the iconic singer performed her first UK show in six years. The self-proclaimed diva, 56, graced the London stage alongside Rita Ora and Will Smith.

During a red carpet interview, Capital Radio's Sian Welby shared that Mariah had completely transformed her dressing room for the event, creating a space called 'Mimi's World' devoid of any Capital branding. Co-host Chris Stark contrasted Mariah's diva behavior with Will Smith's laid-back attitude, highlighting the singer's extravagant requests.

Last year, Mariah was reported to have maintained her diva reputation during her Christmas Time tour, insisting on attractive backup dancers and a full glam squad for rehearsals. The star's demands and behavior have continued to fuel rumors about her extravagant lifestyle.

At the Summertime Ball, Mariah wowed the audience with her hits like Fantasy, Emotions, Hero, Always Be My Baby, and more, culminating in a performance of We Belong Together. Fans praised her vocals and stage presence, hailing it as one of her best performances in recent years.
