Miranda Lambert has been rumored to have cheated on Blake Shelton, but the country star dismissed the rumors to party with Shania Twain during the Rock This Country Tour at the Bridgestone Arena in Nashville on Friday.

Blake Shelton's ex documented her time at the concert by posting a photo on Instagram of Shania Twain performing on top of the crane with the thick crowd below her.

She wrote, "Shania Twain. Fringe Saddle. That's All. #nashville #girlsnight #rockthiscountry #badass #musicismedicine."

One fan wrote, "You are amazing. It is no one's biz why you got a divorce unless you want them to know but making accusations about why they think you did then condemning you 4 it isn't someone you want as a fan anyway. That's the dumbest thing I've heard today!"

Another said, "Appearantly (sic) she cheated on 5 guys at once," referring to Miranda Lambert.

Later, Miranda Lambert partied with Shaina Twain backstage as the two girls hugged it out for the camera. Blake Shelton's ex-wife wrote, "Girls night, love seeing you! #RockThisCountry."

A fan commented, "I. would. have. died. the two queens of country on one stage? heart attack."

Another said, "Was hoping you @shaniatwain and @mirandalambert would share the stage last night! Loved it! I just didn't get a high five as you were coming by me."

Blake Shelton and Miranda Lambert confirmed the divorce news in a statement sent to ABC News.

The statement read,"This is not the future we envisioned and it is with heavy hearts that we move forward separately. We are real people, with real lives, with real families, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."

According to Star magazine, per CDL, Miranda Lambert was allegedly cheating on Blake Shelton with five different men, including his best friend Jamey Johnson, and Josh Beckett, a baseball player.

The source alleged, "Josh was dating his childhood sweetheart Holly when he first got involved with Miranda, Holly may have known about the affair but she married him anyway."

"Even when his new wife got pregnant, Josh still pined for Miranda and pressured her to dump Blake for him. The truth is Josh was Miranda's other real love."
