The pair, who broke up in November 2016 after more than one year of dating, sparked reunion rumours in April when they were spotted kissing at Coachella. Though they've been seen together on numerous occasions since, it appears they're now holidaying together in Tokyo, and don't care who knows it.
Overnight, Bella took to Instagram to share a Story of The Weeknd, writing: "Muse forever" in love hearts.
The Weeknd then took a video showing a laughing Bella at the end.
Though the pair don't yet follow each other again on the social media platform, The Weeknd liked a photo of Bella, which she captioned with his song lyrics last week.
