Willow Smith may not have whipped her hair on the Grammys red carpet tonight ... but she could have!

The 10-year-old brought dad Will and mom Jada Pinket-Smith as her dates to the music awards show. And her bro was there too, peforming Never Say Never with none other than Justin Bieber.

But hold up -- WHY is Willow wearing custom 4-inch platform heels by Louis Vuitton? Has fashion gone too far when a pre-pre-teen girl is wearing heels as high as her mom's???
