Miranda Lambert and Blake Shelton May Have Divorced Because She Cheated (REPORT)

Just one day after Miranda Lambert and Blake Shelton confirmed they filed for divorce, several new reports are suggesting what may have caused the country superstars' breakup.

According to TMZ, the 39-year-old star of The Voice ended things because he believed his former wife, 31, cheated on him not once but twice!

Sources close to the situation tell TMZ Blake believes his wife was unfaithful and had an affair with Chris Young, a 30-year-old country singer who previously opened for Miranda while on tour.

But the sources insist Chris wasn’t the catalyst for the divorce, explaining it was another act of infidelity that served as the straw that broke the camel’s back — as this additional information “elevated things in Blake’s head from rumor to fact.”

Meanwhile, an additional insider close to the couple says they ended their four-year marriage because they had different views when it came to starting a family.

"He is eager to have children, but she really enjoys not being tied down,” the insider tells Page Six.

“I think they both were off on what the time frame would be.”

The former duo are no strangers to the rumor mill. Two years ago, it had been reported that Blake had an affair with up-and-coming singer Cady Groves in 2011, while it was also recently alleged that Miranda feared her husband’s excessive drinking would lead him to cheat.

“Blake says he can handle his alcohol and that everyone needs to stop bringing it up,” another source told Life & Style back in April.

“She is tired of telling him to cut back or get help.”
