Los Angeles, July 18 (IANS): Model Dylan Penn, daughter of actor Sean Penn, feels her father's ex-fiance Charlize Theron is "the best".

Dylan insists she is on very good terms with the 39-year-old actress even though Theron ended her relationship with 54-year-old Sean in May after approximately 18 months of dating.

"She's the best. She's hilarious. She's very bold, in the best way," the 24-year-old model told usmagazine.com when asked about the Oscar-winning actress.

Dylan, who is Sean's daughter with ex-wife Robin Wright, previously praised Theron for being "the only woman since my mom who can shut my dad up".

Cracks are said to have first started to appear in Sean and Theron's romance shortly after they returned here from filming their upcoming movie "The Last Face" in South Africa, but Dylan insists the film, which her father directed and stars Theron, is "a masterpiece".

She said: "He just went back to South Africa (to do) re-shoots for his movie that he did a couple months back. His life is this movie. I've seen pieces of it, and it's a masterpiece."
