Hollywood starlet Charlize Theron will reportedly return home to South Africa to marry famous beau Sean Penn.

According to the Daily Mail, Charlize and legendary actor Sean have decided to kill two birds with one stone by tying the knot this summer while they are already in the country for work on a new film.

Sean is set to direct a new movie called ‘The Last Face’, in which 38-year-old Charlize will play one of the lead roles.

Charlize and 53-year-old Sean haven’t been a couple for very long, but they are believed to have been good friends for some 18 years and sources say he has changed his notoriously wild ways as he has gotten older.

“'They want to get married very soon. Charlize has seen Sean grow up. He’s a wiser soul and much more patient,” said a source.

And the couple are reportedly also planning on adopting a little brother or sister for Charlize’s two-year-old adopted son Jackson quite soon after saying ‘I do’.

Sean was spotted as he arrived in Cape Town on Tuesday to start work on ‘The Last Face’.

A love story, the film tells the tale of two doctors (played by Charlize and Javier Bardem) who meet while providing humanitarian aid in Africa, and revolves around the tough moral dilemmas they face amidst violent civil unrest.
