Billy Ray Cyrus and singer Firerose may be heading down to the aisle.
On Tuesday, the singers shared a joint Instagram post with close-up images of the two in front of a tree bursting with orange leaves.
The couple captioned the post “Happy Autumn🧡.”
But instead of the fall foliage, the focus was instead on the diamond Firerose was wearing on her ring finger.
The rock had fans convinced that the pair were confirming their engagement, but when reached by PEOPLE, a rep for Cyrus had no comment.
Cyrus, 61, and Firerose first sparked engagement rumors when she posted a series of Instagram images on Sept.14, posing behind a wagon wheel while wearing a diamond on her ring finger.
She captioned the image carousel, “Taking in the moment …”
Cyrus’ wife of 28 years, Trish Cyrus, filed for divorce in April of this year, marking the third time they had gone their separate ways.
The pair married in 1993, and share five children: daughters Miley, Brandi, and Noah, and sons Trace and Braison.
