Bono and Denzel Washington brought some superstar glamour to graduation day in New York on Wednesday (22May13) as the celebrated their daughters' academic achievements. The pair was in attendance at Yankee Stadium for the New York University's graduation ceremony, and watched proudly as their girls graduated. The U2 rocker's 21-year-old actress daughter Eve Hewson picked her diploma, as did Olivia Washington. Bono had been offered an honorary Doctor of Humane Letters degree by university bosses, but decided to turn down the honour so he could concentrate on cheering on his daughter's achievements. Washington had double the reason to feel proud - he attended his son Malcolm's graduation from the University of Pennsylvania in Philadelphia last week (13May13). Malcolm excelled at the Ivy League school, playing basketball and earning a degree in film studies.
