Sean Penn's daughter praises Charlize Theron: 'She's the only one who can shut my dad up'

Sean Penn is a lucky man – just ask his daughter, Dylan Penn. The 23-year-old recently spoke about her dad's romance with Charlize Theron, and gave the South African actress her seal of approval.

"She's awesome," Dylan told US Weekly at an event in Hollywood this week. "They've been away for months working together in South Africa, so I haven't seen much of either of them.

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

Asked what makes Charlize so special, Dylan added, "Well, she's brilliant for one thing, and she's the only woman since my mum (actress Robin Wright) who can shut my dad up. The only woman!... She's a powerhouse."
