Blake Shelton and Miranda Lambert: This Is the Real Reason Why They Divorced; Award-Winning Country Music Singer Cheated on Her Ex-Husband With a Married Man?

Blake Shelton and Miranda Lambert's divorce has always been a big puzzle. After being together for two years and appearing happily together on screen, their fans were shocked when they announced their separation. However, new reports claim that Lambert cheated on Shelton with Dierks Bentley, who's married to his longtime wife Cassidy Black.

Everyone was reportedly caught off-guard by Blake and Miranda's divorce that even Carrie Underwood claimed that she asked her husband, Mike Fischer, to assess their strong relationship, Classicalite reports. Rumors have it that Lambert is dating Dierks casually. It could reportedly be noticed when they are together, sources added.

"She and Dierks are both party animals... And now that Miranda doesn't have to answer to anyone anymore, she's completely letting loose. This buzz that Dierks and Miranda are hooking up is very upsetting to his wife. Cassidy has been with him long enough to know what he is like, but watching his behavior with Miranda lately has caused tension in their relationship," said an insider.

Although Blake and Miranda have never spoken about their divorce, "The Voice" coach was often cast in a negative light, as he was linked to Cady Grooves and even Gwen Stefani, Movie News Guide reports. The new angle in the ex-couple's divorce is said to be causing a strain in Dierks' strong relationship with his wife, as they now reportedly often fight because of his closeness with Blake's ex wife.

They apparently left tongues wagging when they didn't even shy away from being close to each other as they posed for photographs.
