Padma Lakshmi at the BMAs
Is it any surprise that Padma Lakshmi looked amazing on the red carpet? No. Of course not.
Tyra Banks at the BMAs
Tyra Banks is always very comfortable on a red carpet. She might as well have been born on one.
Jennifer Lopez at the BMAs
Does someone want to tell Jennifer Lopez that her bra is showing? Do you think she's aware or not?
Kesha at the BMAs
Kesha has been known to rock some unique looks. What do you think of her Billboard Music Awards selection?

Talk about a true icon. Janet Jackson plays it cool here while someone works on her gorgeous dress.
Alyson Stoner at the BMAs
Go bold or go home, right? This was clearly the thought process here of Alyson Stoner.
Mila Kunis at the BMAs
Yes, this really is a photo of Mila Kunis. We checked! She looks rather different, doesn't she?
Shawn Mendes at the BMAs

Ciara at the BMAs
Ciara has never been afraid to show a bit of skin. And for good reason, as you can see here.
Christina Aguilera at the BMAs
Well... okay then! Christina Aguilera certainly went bold at the Billboard Music Awards. Is this a winning or losing look?

Halsey only needs one name to make an impression. And just one signature pose to stand out on a red carpet.
Jenna Dewan at the BMAs
