I know that P. Diddy's birthday parties tend to have unusual dress codes, but given all the other photos I've seen, it was definitely not in any way necessary for Mariah Carey to show up in a wedding dress:
Somebody has a Princess Diana complex.
There are lots of white dresses out there. Indeed, there are lots of colorful dresses with fur accoutrements, which is what a lot of other party guests wore. So why Mariah went to David's Bridal and picked out a marshmallow fantasy frock is quite beyond me.
Although when you're famous, I guess you never know when a wedding might break out, so I suppose it makes sense to come prepared.
The woman is clearly off her rocker. Let's hope though, that the tales about her enormous entourage are true. I can see a whole load of candles on the floor, and it would surely take a whole team of flunkies to keep la Carey from setting her self on fire and shrink wrapping herself in that nasty, nasty dress.
