As the battle rounds continue to heat up on NBC’s hit singing reality competition show, The Voice, Breaking Celebrity News has exclusively learned that the REAL battle is being waged backstage – between celebrity couple judges Gwen Stefani and Blake Shelton!

“Gwen and Blake are actually becoming really competitive with each other this season and it is quite fun to watch,” a production insider told Breaking Celebrity News.

“Whereas they used to help each other and kind of be on the same team, they are both really out to win it this time around."

As Breaking Celebrity News previously reported, Stefani, 47, and Shelton, 40 – who started dating in Nov. 2015 in the wake of their high-profile splits with exes Gavin Rossdale, 51. and country singer, Miranda Lambert, 33, respectively – were offered a massive cash bonus to keep their flirtation going strong on the current season.

However, according to the insider, that has not been easy for the mother of Kingston, 10, Zuma, 8, and Apollo, 3, and her country-crooner man candy to do!

“They have been arguing a lot backstage when the cameras are not rolling,” the source told Breaking Celebrity News.

“Blake and Gwen are not calling each other cutesy names like they used to and they are not acting all lovey-dovey like they have been in the past!”
