Country music stars Blake Shelton and Miranda Lambert are calling it quits. According to TMZ, Blake Shelton filed for divorce because he believed Miranda Lambert was unfaithful, not once but twice. Blake heard rumors that Miranda had allegedly hooked up with country singer Chris Young and thought it was believable enough to make him suspicious of her. Young had opened for one of Miranda’s shows a few years ago, and the two were spotted publicly from time to time. Do you believe Miranda was unfaithful to Blake?
