While Miley has yet to open up about the shock split, a source told Entertainment Tonight that the singer “wasn't thinking long term and when Kaitlynn realised Miley was done, it was a total shock."
Miley and Kaitlynn's romantic relationship first blossomed in August after photos emerged of the pair engaging in public displays of affection on a vacation in Italy.
According to PEOPLE magazine, a source confirmed the news of their split last week, telling the publication that, "Miley and Kaitlynn broke up" but the former lovers are "still friends."
The same source claimed that the two found comfort in each other after their respective marriages broke down.
This is the Slide Away singer's second major breakup this year, having split with husband Liam Hemsworth in August, after less than a year of marriage.
Kaitlynn split with former husband Brody Jenner the same month.
Although Miley and Liam's separation was also reportedly amicable, an insider recently told Page Six that Liam— who was in Australia when the news broke— was "blindsided" by Miley and Kaitlynn's relationship, as the former couple hadn't decided on when exactly they planned to tell the world.
