Among the sea of famous faces, Rita and Iggy seemed to stand out the most. The two friends were having fun catching up on the red carpet, and both looked fiercely sexy.

Iggy showed off her curvy figure in a bright orange Cushnie et Ochs Resort 2015 bandage dress that features slits and cutouts on the back and sleeves.

Rumored to have undergone plastic surgery, she paired the frock with nude pumps and styled her hair in a sleek and high ponytail.

Considering that this girl always wears bold and sometimes over-the-top sexy ensembles, this orange number is actually one of the classiest dresses she has worn.

Brit superstar Rita, on the other hand, looked extra fierce in a black number that features fringe detailing on the hem.

The more petite singer also has a rocking bod, and her Hervé Léger by Max Azria Fall 2014 dress totally showed off her lean frame.

We love how Rita styled her short do — sleek and sexy. Plus, the silver-tone choker amped up the fierceness of her ensemble.

Don’t you wish she had chosen a different pair of shoes? Her edgy dress would look a lot better with sexy sandals instead of those black-and-white pumps.
