Although the former couple insists they’re both fine following their divorce after four years of marriage, Blake Shelton and Miranda Lambert’s sanguine nature will be put to the ultimate test. It’s been announced that the ex-husband and wife will make their first joint public appearance since announcing their split in July.

According to E! Online, Shelton was announced as one of the performers set for the Country Music Association Awards on Nov. 4. The live event, hosted by Brad Paisley and Carrie Underwood, will feature such performers as Jason Aldean, Luke Bryan, Sam Hunt, Kelsea Ballerini, Maddie & Tae, Kacey Musgraves and, of course, Miranda Lambert. This will mark the first time that the former couple has appeared in the public eye on one stage since the split, and the rumor mill has had a field day in the months since.

“The Voice” coach Shelton has been hard at work on Season 9 of the hit reality competition, and the divorce hasn’t stopped his career one bit as he’s personally nominated for two CMA Awards. Although the breakup has sparked countless rumors indicating that he’s dating fellow “Voice” coach Gwen Stefani, the former No Doubt singer shut those rumors down while speaking to "Entertainment Tonight."

Meanwhile, Lambert has been pouring her heart into her own music. The “Little Red Wagon” singer is nominated for four CMA Awards including the highly coveted Entertainer of the Year award. Fortunately for people tuning in for the music and not the controversy, odds are good there won't be an all-out blowout between the former husband and wife. Shelton and Lambert, to their credit, have been amicable since their split. Speaking on the Bobby Bones radio show, Shelton made it clear there were absolutely no hard feelings between the two and they were making an effort to make their divorce as little a deal as possible.

“Our whole thing was: You know, we’re just going to be cool about this. It is what it is,” he said. “We’re buddies.

The 49th annual CMA Awards air live Nov. 4 on ABC at 8 p.m. EDT.
