The marriage of country music star Blake Shelton and fellow singer Gwen Stefani is rumored to be on the rocks after they spent the New Year separately. Shelton performed at the New Year’s Eve Live: Nashville’s Big Bash on CBS, while Stefani sang on December 31 in Las Vegas, Nevada. An insider close to the couple warned that their marriage is in trouble. The tension continues to grow, and they are drifting apart. Shelton divulged last month that he wants to either cut back or stop drinking altogether. He claims Stefani has become ‘a country girl’, while Stefani claimed to be loving life in Oklahoma. This is Shelton’s third marriage and Stefani’s second, with each of them ending in divorce. Let us know your thoughts in the comments section.
