No cattiness from this ex!

Sean Penn's former girlfriend, supermodel Jessica White, is happy for the actor's new romance with Scarlet Johansson. White, 26, tells PopEater in an interview, "Yes, they're great together!"

The Sports Illustrated model dated the Oscar Winner, 50, off and on in 2009 and 2010, and she claims they are still pals. "Sean is a really lovely man," she says, adding, "I think Sean needs a good woman in his life." Penn divorced wife Robin Wright after 14 years of marriage in August 2010; they have two kids together--Dylan Frances, 20, and Hopper Jack, 18.

Penn and Johansson, 26, began their fling in early January, just weeks after her hubby Ryan Reynolds filed for divorce after two years of marriage. Although the duo kept their fledgling romance private for the next several weeks (despite a PDA-packed trip to Mexico and nights out in Hollywood), they finally made their debut as a couple before a crowd of A-listers-- at Reese Witherspoon's star-studded March 26 wedding.

White offered additional insight into her outspoken, sometime-volatile ex, explaining that his true "calling" is his humanitarian work in Haiti.

"That's where he finds his peace and refuge. I think that's a great job," she says. "He's very passionate."
