WATCH: Mariah Carey Meltdown: Diva’s Voice Is Shot

Mariah Carey has been caught with her voice creaking in a shocking new video — just as the "under stress" pop star is being blasted for diva antics on a film set!

Sources told The National ENQUIRER that Mariah now refuses to go anywhere without a stuffed animal collection at the ready! “Mariah relies on her collection of cute stuffed animals as a source of comfort,” an insider spilled. “They’re intended to calm her down in high-stress situations.” And a Hollywood actor backed up the shocking story!

Actor Rob Huebel went public with shocking claims about Mariah's diva demands on the set of "The House." Mariah was hired to play herself in the new Will Ferrell comedy, with Rob saying she quickly alienated the cast by showing up "four hours late" for her one-day shoot, and demanded stuffed toy lambs in her trailer!

Rob also reported that Mariah demanded "all-white roses" — and argued with producers over the script. “They were like, ‘Mariah, we don’t have time for [this],” scoffed Rob — adding that Mariah even argued about her own song that she was hired to sing!
