AceShowbiz - Evan Felker has updated her Instagram account with a cryptic post following reports that her estranged husband has cheated on her with Miranda Lambert. Staci Felker seemingly reacted to the affair allegations with a heartbreaking Instagram Stories picture.

In the image posted on Thursday, April 26, Staci looked straight to the camera with her eyes slightly glazed as if she had just been crying. She wrote on it, "PSA: If Staci Felker can make it through this week, so can you."

Evan posted the Instagram Stories just a few days after reports emerged that her estranged husband Evan, whose band Turnpike Troubadours has been supporting Miranda during her tour, has been unfaithful to her. The folk singer is reportedly dating the "Mama's Broken Heart" songstress following her split from Anderson East.

A source told Us Weekly that the two are "very much involved." Another so-called insider claimed that Miranda and Evan "started spending a lot more time together while on the road," noting that things just "happened" between them while Miranda had not officially split from Anderson.

Evan and Staci got married in September 2016. She filed for divorce from the Turnpike Troubadours frontman a month after he started touring with Miranda. The insider added, "Staci had no other choice but to file for divorce. She was devastated."

A source close to Felker, however, said that it was Even who filed for divorce first on February 16, while Staci responded 12 days later.

Blake Shelton recently appeared to shade his ex Miranda following reports of her alleged affair with Evan. "The Voice" coach tweeted, "Been taking the high road for a long time.. I almost gave up. But I can finally see something on the horizon up there!! Wait!! Could it be?! Yep!! It's karma!!"
