Charlize Theron and Sean Penn coupling may have broken Keanu Reeves' heart since the actor had been in an on-off relationship with the beauty.
The 39-year-old star, who's now engaged to Penn, was involved with the 'John Wick' star, 50,after they met on the sets of their romantic movie 'Sweet November'.
According to OK magazine, an insider said that Theron's falling in love with Sean really hurt Reeves as he had assumed it would be them who would eventually end up together for good.
He's a little heartbroken, but definitely wants Theron, who's scheduled to get married to Penn by the end of this year, to be happy, added the source.
