EXCLUSIVE PHOTOS - Sean Penn Is Ready To Propose To Charlize Theron

Is Sean Penn about to propose to Charlize Theron?

Not only has he been acting like a father figure to Charlize's son Jackson, but he introduced his mom Eileen to his new lady love.

Sean Penn took his mom, Charlize, Charlize's mom Gerda and Jackson to brunch in Malibu on Sunday. He also accompanied Charlize and her mom to see Chelsea Handler's live standup show "Uganda Be Kidding Me" on Saturday night and planned an outing with Charlize and Jackson at a Los Angeles Dodgers game last Sunday. Now that's a lot of family time.

Although they just went public with their romance in February, the relationship seems to be getting more serious by the minute. Despite their 15-year age difference, the two actors have a lot in common, including their philanthropic work.

Sean will direct his girlfriend in the love story The Last Face, which will start filming in South Africa later this year. Seeing as Charlize was born in Benoni, South Africa that would be as perfect of a time as any to pop the question.
