Reports: Sean Penn wants to adopt Charlize's little boy

Could this be the beginning of a big happy family for Sean Penn and Charlize Theron?  Sean Penn has apparently filed papers to adopt Charlize's son, Jackson.

People magazine recently reported that Sean has started the process in order to secure a happy family for him and Charlize.

"Charlize and Sean are very serious. Charlize says this is it. Jackson already calls Sean daddy. This is the first step toward them getting married", says the source

But other sources have said that it's still early days for Sean's adoption plans and that he still plans to adopt Jackson, but has not started the process yet.

We not sure who to believe. After all, no one is even clear whether the pair are engaged!

Either way, Sean seems committed to making things work with Charlize. Good on him!
