Sean Penn and Charlize Theron have been dating for just over a year, but could they be taking steps to become family? According to reports Sean has filed papers to adopt Charlize's three-year-old son Jackson, in the ultimate sign of commitment to his rumoured fiancée.
"Charlize and Sean are very serious," a source told People. "Charlize says this is it. Jackson already calls Sean daddy. This is the first step towards them getting married."
The couple, who were rumoured to have got engaged in November, are also said to be thinking of adopting another child together in the future.

Charlize adopted Jackson in 2012 when he was four months old, while Sean also has a daughter, Dylan, and son, Hopper, from his marriage to Robin Wright.
The couple have avoided discussing their relationship since going public at Sean's annual Help Haiti Home Gala in 2014. Sean remained coy when quizzed about engagement rumours in January and avoided giving Extra host Jerry Penacoli a direct answer.

"She and I have been very, very long-time friends. We hit a speed bump and must have lost our minds, so here we are."
