Robin wright Penn

Robin wright Penn, Sean Penn's daughter thinks Charlize Theron is "a powerhouse." Dylan Penn admits the Oscar-winning actress, who started dating her father late last year, reminds her of her mother, Robin Wright, who split from Sean in 2010, because they're the only women who can shut the 'Milk' actor up.

The 23-year-old model told UsMagazine.com: "She's awesome. 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's happy, I'm happy for both of them."

Asked what she likes about the blonde beauty, she added: "Well, she's brilliant for one thing, and she's the only woman since my mom who can shut my dad up. The only woman! That is a f**king challenge so... She's a powerhouse."

The couple, who went public with their relationship in January, are currently shooting the drama 'The Last Face' in Charlize's native South Africa.

A source previously claimed that Sean and the 'Prometheus' actress, who has adopted son Jackson, three, are already talking about getting married.

Meanwhile, Dylan, who was once linked to Robert Pattinson, is currently on the hunt for a "funny, smart" boyfriend.

She said: "I really don't go off looks but I am into height. I would like them to be a little taller than me. They don't need a good body or anything. I always look at hands or someone's back. If a guy has good hands I'm all about it. Veiny, big hands."
