Country singers Tim McGraw and Faith Hill celebrated their 18th wedding anniversary on Monday, and while divorce rumors still spiral, the couple continues to moon over one another both publicly and privately.

On Tuesday The Inquisitr ran a story that claimed the couple were struggling after McGraw relapsed back into substance abuse, which could be the reason for his recent weight loss.

Any photo or interview, however, would contradict this claim and prove that after 18 years the country duo is still going strong.

Tim McGraw Dishes On His Wife's 'Passion'

"Anytime I get to see my wife perform, it [Breathe] just transfixes me," declared McGraw in an interview with People back on Sept. 17 in talking about his wife's own career and her 1999 hit Breathe.

This year not only marks the singers' 18th anniversary, it is also the year in which they released a new single together of his Sundown Heaven Town album.

In discussing the origin of the song with People, McGraw admitted that he played the piece for his wife before deciding that they just had to perform it together. "When it got to the end, where it said, 'Me and you back at Mama's', she just started crying," remembered McGraw. "I said, 'I'm going to record it and you're going to record it with me.'"

The decision paid off both personally and professionally as Meanwhile Back at Mama's soon became McGraw's 50th song to hit Billboard's Top Ten for country music.

"We really haven't recorded that many songs together," continued the singer. "Just a handful. And we try to only record songs that we think are special to us. And this is one of those songs."

Married in 1996, Tim McGraw and Faith Hill celebrated their 18th wedding anniversary on Oct. 6, 2014.
