Worrying about PDA is not an issue for married country stars Blake Shelton and Miranda Lambert. 

How Miranda Lambert Is Beating Out Blake Shelton With Latest 'Milestone' Achievement 

On Sunday the couple posted a cozy selfie on Twitter to show some support for the band Little Big Town and their latest single Girl Crush.

 Miranda Lambert's Drinking Buddy Says She's A 'Traditional' Country Star 

The 31-year-old Somethin' Bad singer's showed support after Girl Crush was pulled from a few radio stations because some listeners had complained about some of the sexuality in the lyrics. The photo happens to come just days after Shelton opened up about the video for his new song, Sangria, which the 38-year-old has been calling "pure sex".

"Sangria is one of the sexiest songs I've ever cut…" he told People on Friday. "It's just about one of those nights where you drink too much and you're gonna end up hookin' up with this person, it's just inevitable.

"It's not too over-the-top," insisted Shelton of the single, "But it's pure sex. That's the only way I know to describe that song."

Shelton and Lambert might be out touring separately this week, but that doesn't mean the two aren't still thinking about each other. Shelton told New York City fans on Twitter that they were "lucky" because they were able to see Lambert perform at Madison Square Garden. Of course Shelton himself couldn't be there, but he did send flowers which Lambert absolutely adored.

Both Shelton and Lambert will continue performing across the country over the summer, finishing with the WE Festival in August.
