The couple last month, while vacationing in Paris, "decided to take their relationship to the next level,” a source told US Weekly. “There's no ring, but they are committed.”
Penn, 54, and Theron, 39, began dating a year ago, and gradually have taken things up a notch as time has passed. An insider told RadarOnline.com back in February that after “the two began talking about marriage,” Theron closely watched how well Penn interacted with her 2-year-old son, Jackson.
The romance hasn’t come without a small measure of skepticism, as Theron’s pals urged “her to think twice before finally heading down the aisle with Sean,” a source told The National ENQUIRER, due to his past issues with domestic violence.
