"He's dating, he's got a girlfriend," the notoriously private Angelina, 38, surprisingly dished to ET.

And both Angelina and Brad approve!

"She's great," she smiled. "I won't embarrass him. She's lovely. She lives in England. She's very cool."

And how do the two keep their long-distance love going?

"We go there as often as possible. It's really, really sweet," she said. “She's a great lady, so I'm lucky. So far, we're doing good."
