On the red carpet on Sunday, Nyong'o, 31, told Associated Press: "I'm just wearing my diamonds and pearls. My homage to (musician) Prince."

She added of the dress: "We talked about it being fluid and liquid. I wanted it to be an homage to the sea."

No arrests have been made.

Calvin Klein has not commented.
