Irina Shayk: Cantamessa Jewels Launch!

Irina Shayk hits the red carpet at the Cantamessa Jewels U.S. launch on Thursday (April 28) at the Manhattan Motorcars Showroom in NYC.

Earlier in the day, the 25-year-old Russian model signed copies of her Sports Illustrated swimsuit issue for the Red Cross at the Trump Soho Hotel.

Irina recently served as StyleBistro‘s guest editor and was asked what her definition of “sexy” is.

“[It] is very simple: You need to be yourself, natural, the way you are. It’s the most attractive thing in the world. People who love themselves the way they are are always very sexy and attractive,” she shared.
