Charlize Theron and Sean Penn made an unusual couple, but one that many believed just might stand the test of time. That belief has now been shattered.

Multiple reports say that the two have called it quits.

Last spotted on the Cannes red carpet in May, Sean Penn and Charlize Theron spent much of their down time in the company of her three-year-old son, Jackson. Since Cannes, however, they haven’t been spotted together in public at all.

Sources say the two have lived at separate addresses since returning from Cannes. Charlize Theron and Jackson lived in their Hollywood home, while Sean Penn stayed at his mansion in Malibu. He had previously put that mansion up for sale but withdrew it from the market upon his return from France. Prior to the trip to Cannes, the two were inseparable–often spotted at events where she was promoting her film Mad Max Fury Road.

It was only about a month ago when Charlize Theron called Sean Penn “the love of my life” during an interview with British Elle.

“Putting aside that he’s my partner, he’s the love of my life; for the first time, I felt that my work was really bleeding into my life, and that made it hard,” she said at the time.
