Sean Penn's Daughter Explains Why Charlize Theron Is Her Dad's Perfect Match

"She's great and they're amazing together," Dylan Penn gushed.

Now, she's explaining why.

"Well, she's brilliant for one thing," she told Us Weekly. "And she's the only woman since my mom [Robin Wright] who can shut my dad up. The only woman! That is a f***ing challenge so ... She's a powerhouse."

Because of the distance, Dylan said she hasn't seen them recently, but added that Theron is "awesome."

"She's great and they're amazing together," she said. "As long as my dad's happy, I'm happy for them."
