Sexy Stars: Rita Ora wears lingerie and Priyanka Chopra is a stunner in navy blue

She wore what?!

Stars got racy in their respective red carpet looks this week -- and some more than others.

It seems like Rita Ora forgot to look in the mirror before leaving home. The singer hit the red carpet wearing ... lingerie. Nonetheless, she rocked it with no shame.

"Quantico" star Priyanka Chopra was a stunner in blue at a UNICEF event. The actress paired the figure-hugging dress with a sexy red lip.

Of course, Ashley Graham oozed sex appeal at a Sport's Illustrated event, wearing a sequined pink-and-black frock. The model flashed major cleavage in the tight number.
