The two artists reportedly had a falling out when Lovato's manager, Scooter Braun, acquired Swift's former label, Big Machine Label Group -- and by extension ownership of her master recordings.
That same day, the "You Need to Calm Down" singer lamented on her personal Tumblr that the buyout was her "worst case scenario" and accused Braun of being a manipulative bully.
That post drew a proverbial line in the sand that seemingly forced artists to pick a side. Lovato defended her manager, which drew the ire of Swift's super fans. Now, it seems the alleged dispute is over because Lovato is loving "Lover."
She expressed her praise on her Instagram stories, starting off with a screenshot of her playing Swift's "Cruel Summer," calling it "A Jam."
Lovato then wrote to Swift: "Life's too short for women to not support other women ... especially when women release great music. Great job."

Swift responded on her own Instagram stories, saying Lovato's post "put the biggest smile on my face."
"Lover" is Swift's sixth No. 1 album, tying her with Lady Gaga for the most this decade among female artists at five each.
