Taking to Instagram and Twitter, Rose shared a heartfelt letter with her fans which revealed the two stars had parted ways months ago.
The Pitch Perfect 3 star, 32, and Origliasso, 33, began dating in November 2016 after they rekindled their previous romance from a decade ago.
“Breakups are always incredibly hard on the people involved but I can only be grateful for the experiences we shared,” Rose wrote to Twitter.
Origliasso is yet to break her silence on the matter. She last shared a snap alongside Rose on March 4.
Sending love to both stars during this difficult time.
