The 'Pitch Perfect' actress and YouTube comedian have decided to go their separate ways just four months after they went public with their relationship but insiders believe there is still a chance they will reconcile in future.
A source close to the couple told Us Weekly magazine: "It's been hard for him. They're still friends, so you never know if they might get back together in the future."
News of the split comes just a month after it claimed the 35-year-old actress and her 'How To Be Single' co-star - who were first spotted on a date in June - were planning to marry at the Graceland Wedding Chapel in Las Vegas later this year.
A source said recently: "'They're looking to get married later this year.
"They are just going to invite their nearest and dearest and a few celeb friends. She just wants everyone to let their hair down and have fun in Vegas.
"Rebel doesn't want a traditional ceremony and neither does Mickey."
In July, the couple enjoyed holidays to both Spain and Dubai, with Rebel boasting about the their European adventure which saw them visit party island Ibiza and Gothic city Barcelona in the northern province of Catalonia.
Rebel captioned a selfie of herself and Mickey on Instagram: "Fun & Sun in Ibiza right now!! Thanks Hard Rock Hotel @hrhibiza #hrhibiza #ThisisHardRock."
