Nicole, 53, paid tribute to Keith, 53, with a photo of the couple sharing a tender moment in a beautiful, countryside setting.
In the picture the lovebirds have their heads leaned into one another and their eyes are closed. Nicole appears to be kissing Keith’s cheek as he smiles adoringly.

The star captioned the sweet snapshot: "Listening to Keith’s new album feels a little something like this."
She was unable to be with Keith as she’s currently in Byron Bay, Australia, but she logged on to view his performance in Nashville from a laptop.
Nicole and Keith have been forced to spend time apart
Keith has been promoting his album The Speed of Now: Part 1 over the last few months ahead of its release on 18 September.
He explained the inspiration behind the title in a video posted to his YouTube channel earlier this year.
"In October 2019, this title came to me: The Speed of Now," he said. "I liked it because I felt like life was flying by so fast. Faster and faster all the time."
"But music, for me, has always been the place where it slows down and doesn't even exist. I would never have imagined that, in 2020, this album title would take on a whole new meaning and yet somehow still feel incredibly relevant."
The couple are more in love than ever
Until recently the couple were together during the COVID-19 lockdown in Nashville with their two daughters, Sunday, 12, and Faith, nine.
While it was an unusual situation for the family, Nicole revealed in an interview published in HELLO! magazine that she enjoyed it.
"Staying home, doing school from home and all of those things that everyone has been doing is a completely different life for us," she said before adding: "I love being in the kitchen in the morning so that when my kids come down, there's noise and there's joy in the home. That's really important to me."
