Gwen Stefani may have chosen work over celebrating New Year's Eve with husband Blake Shelton, and inside sources say their marriage may be on the rocks. With Blake announcing a special night of country music without mentioning Gwen's huge Coachella reunion news, fans have raised eyebrows and wonder if the couple is headed for trouble. While Blake publicly made a resolution to cut back on drinking, many speculate that the real reason their marriage is on the rocks is due to their differing careers and priorities.
