Diva smackdown: Madonna vs. Mariah

Public meltdowns

Back before celebrity meltdowns were so common that VH1 could build entire shows around them, a very manic Mariah Carey went on “TRL” in 2001 and freaked out Carson Daly by taking off her clothes, handing out popsicles and saying things like, “I just want one day off where I can go swimming and look at rainbows and like, eat ice cream.” She checked into a mental health facility a few days later. Madonna, on the other hand, has never really had a public meltdown, unless you count one of many scenes in the 1991 documentary “Truth or Dare” where she goes ballistic backstage over various technical problems.

Advantage: Madonna. Despite nearly three decades of public scrutiny, she’s never really allowed the façade to crack.
