The rumor mill is certainly a buzz as multiple outlets claim that Charlize Theron and Sean Penn are taking their relationship to the next level.

A source told press that the couple of seven months wants "to get married very soon. [They] always intended to have another child."

Earlier this week, the Oscar-winning actress stepped out at LAX International Airport rocking a pretty big diamond her left finger, leading plenty to speculate an engagement.

Theron spoke of the relationship to Vogue last month and said, "It just kind of naturally happened, and before I knew it, I was in something that was making my life better—the people who really love me can see the effect it has had on me.”

If the rumors are true, this will be the first marriage for Charlize and the third for Penn.
