After nearly four years of marriage, country couple Miranda Lambert and Blake Shelton are not shying away from PDA.

On Sunday, the 31-year-old Lambert posted an Instagram photo of the two locking lips – and Shelton, 38, looks pretty happy about the kiss!

The pair are both wearing “Girl Crush” caps from Little Big Town in the photo, which is also captioned “We love @littlebigtown.” LBT’s new single has come under fire from some listeners for the mistaken assumption that it is about a lesbian relationship. A few local DJs even refused to play the song.

Reba McEntire posted a similar show of support on her Instagram Friday.

Lambert and Shelton were married in May 2011. She told Marie Claire recently that her husband was “the happiest person on the planet.”

“I’m not sunshine and roses,” she said. “Blake’s the happiest person on the planet. He pulls me out of my darkness Literally, everything is the best about being married.”

Lambert is in the middle of her nearly 30-city “Certified Platinum” tour, and performed in New York City on Saturday night. Shelton, meanwhile, will next host the Academy of Country Music Awards on April 19 with Luke Bryan.

Even better for Lambert: Shelton just premiered the video for his latest single, “Sangria,” which he calls “one of the sexiest songs I’ve ever cut.”
