Leonardo, who?

Sports Illustrated supermodel Bar Refaeli looked sexy as ever when she walked the red carpet at the Diamonds Are a Girl's Best Friend event in Cannes, France on Monday. Wearing a navy blue sequined Roberto Cavalli mini-dress, the 25-year-old beauty showed no signs of heartbreak after her recent breakup with actor Leonardo DiCaprio, 36.

Perhaps Refaeli will run into her ex during the Cannes Film Festival: DiCaprio was spotted on a yacht with pals Steven Spielberg, Kate Capshaw, Blake Lively and Lukas Haas on Tuesday.

Dating for five years, Refaeli and DiCaprio split for six months in 2009 before rekindling their romance the following year.

"It was a half year for which I am very grateful," Refaeli told Israel's L'Isha magazine in March 2010. "I needed it. I came to understand a lot of things about myself."
