Miranda Lambert and Blake Shelton Breakup Buzz: Report Claims Drinking to Blame?

The latest buzz is that the couple is "drinking their marriage away," according to a new report from Star magazine. Blake and Miranda, who have been married for two years, have faced numerous breakup rumors before, but is there any truth the pair are heading for divorce? Star claims, "Though partying is something Miranda and Blake bond over, friends say it's only served to amplify Miranda's jealousy and Blake's uncontrollable flirting--leading to a vicious cycle of drinking, fighting and drinking more as a means to cope."
