Rumors have plagued their marriage for years, but Tim McGraw and Faith Hill are continuing to prove that there's still no trouble in paradise after nearly 19 years as husband and wife.

McGraw shared a selfie with his wife on Instagram over the weekend which showed the two of them making kissy faces for the camera as they sit in front of a sunset.

The two have contended with a fair share of rumors over the years about their marriage, with countless claims of an expensive divorce splashed across the tabloids, which the couple have fought each time by revealing that they were happy in their marriage-though Hill has previously admitted she doesn't think they have any real secret to their marital success.

"I don't think there's a secret," she said back in 2012. "You just have to love the skin you're in, basically. You have to walk this life together. There will be times, ups and downs, but you have to essentially like the person that you love. I think it's important to laugh a lot and have a good time. Life is so short. It sounds contrived but it's the truth."

The couple has been married since October of 1996. Together they are the parents of three daughters, Gracie Katherine, 18, Maggie Elizabeth, 17, and Audrey Caroline, 13.
