Charlize Theron and Sean Penn Split Update: Oscar-Winners Call Quits After Cancelled Engagement

Charlize Theron and Sean Penn reportedly called off their engagement after their excursion and loved-up appearance at the Cannes Film Festival in the South of France.

A source told US Weekly that it was the 39-year old actress who broke up with 54-year old Sean Penn.

The news outlet had also exclusively learned about their secret engagement in December last year while they were on a trip to Paris.

"There's no ring, but they are committed," as an insider said.

Reasons of the split were also not elaborated but sources said that the couple stopped being together in these last few weeks, Time reports.

Rumors further said that they were not living together in the same house anymore with The Huntsman actress and her son, Jackson staying at their Hollywood home without Sean.

The award-winning actor, on the other hand, is said to be staying at his Malibu mansion. The place was previously auctioned but it was reported that Penn changed his mind and would not sell it anymore.

Media had last spotted the actor in the Brentwood section of Los Angeles Tuesday going solo.

The couple is said to have been supported for each other in their film and humanitarian projects.

Once in an interview with CNN, Theron gushed about how much she and Sean have a similar interest in extending humanitarian work, The Daily Beast said.

"A lot of people want to tell you the answer to solving all of Africa's problems from what they've seen on CNN. Sean is not that guy. When he started working in Haiti and I started working on the AIDS front in South Africa, we spent a lot of time talking about those worlds," she said.

The 54-year old actor who previously had two marriages-one with Madonna and the actress Robin Wright considered his supposed marriage with Theron as his first, US Weekly remembered.

"You say I've been married twice before, but I've been married under circumstances where I was less informed than I am today. So I wouldn't even consider it a third marriage, I'd consider it a first marriage on its own terms if I got married again. I mean, I like the tradition. A friend of mine wrote a line, 'Without tradition, new things die.' And I don't want new things to die," the actor said.
