KRISTEN, RUPERT & ROBERT

The rumors: Kristen Stewart and Robert Pattinson's three-year relationship was rocked by scandal in July 2012 when Stewart admitted she'd cheated with her married Snow White and the Huntsman director, Rupert Sanders.
The aftermath: K-Stew issued a public apology to her Twilight love, and Sanders also apologized to his wife, actress-model Liberty Ross, and their two children. After a two-month break, Stewart and Pattinson reconciled and seemed back on track, with the pair most recently celebrating Stewart's birthday together in April and even holding hands at Coachella. But things took a drastic turn weeks later, with sources confirming to PEOPLE on May 18 that the couple has called it quits – for now.
