2. Kristen Stewart & Robert Pattinson
Everyone once swooned at these “Twilight” co-stars finding happiness with each other – until it all shattered with K-Stew’s shocking proof of infidelity, caught on camera! She was caught smooching Rupert Sanders, the director of “Snow White and the Huntsman”. They tried to fix a broken relationship after, but it didn’t work and they split in 2013, leaving FKA to pick up the pieces.
