So, are there wedding bells in the future for Charlize Theron and Sean Penn? A source said "Sean is head over heels in love with Charlize, and her son Jackson. He is a totally different person around Charlize, she brings out the gentle and fun side that not many people have seen of Sean. To see this previously surly grown man, romping around Charlize's backyard with Jackson, with a smile on his face would amaze Sean's detractors. Charlize is getting Sean to not take himself too seriously."
The source said Sean and Charlize are already talking about getting married. Sean Penn and his ex-wife, Robin Wright, have two children, Dylan, 23, and Hopper, 20.

The source said Sean has expressed interest in adopting Jackson.

The insider continued "The two began talking about marriage in the last few weeks, after Sean moved into Charlize's house. She has never wanted to get married, but seeing how Sean interacts with Jackson, she is having a change of heart. For the longest time, Charlize thought it was just going to be her and Jackson, and she was OK with that. For her to now be talking about getting married is a huge departure for Charlize."
