Bring it on.

Blake Shelton and the Westboro Baptist Church's longtime feud was re-ignited on Tuesday, when the 39-year-old country superstar responded to the group's plan to picket his Friday concert in Kansas City. The religious sect -- best known for picketing military funerals and their anti-gay messages -- tweeted that they'll be protesting his upcoming show at the Sprint Center in Missouri.

"Great!!!! Lots of my crew guys will be happy to see your wives.. Again.," Shelton cracked.

This, of course, isn't the first time Shelton has taken on the controversial religious group. When Westboro targeted the singer in September 2013 for his then-marriage to singer Miranda Lambert after divorcing his first wife, Kaynette Gern, in 2006, Shelton fired back.

"Y'all may want to keep an eye on ur women at my show.. I've got a few band and crew guys that'll be smacking that holy a--!" he tweeted when the group said they were planning to picket his show in Kansas City at the time.

"Hey @WBCSays.. This isn't about God," Shelton added. "It's about me using this opportunity to make y'all look like the absolute complete dipsh--s you are."

Clearly, Shelton's got plenty going on in his life aside from the Westboro drama. The "Voice" coach has been dating Gwen Stefani since last November, and the two couldn't appear more in love. Most recently, the pair celebrated Stefani's son Apollo's second birthday together, with a cowboy-themed party held at the "Make Me Like You" singer's Beverly Hills, California home.

"[They had their] arms around one another, and [gave each other] little kisses on the cheek," an eyewitness at the "happy and festive" party told ET about the couple. "Blake was very hands-on with the kids, playing and walking around with them."
