There's a catfight between The Voice season 12 judges Alicia Keys and Gwen Stefani. As fans of the popular NBC singing reality completion show already know, Stefani (Blake Shelton's girlfriend) replaced Miley Cyrus as a judge for the next season.

While Adam Levin and the rest of the cast and crew are super excited for the "Hollaback Girl" to return to The Voice, Keys is not at all pleased about the switching of the divas since is in a tight friendship with Cyrus.

The insider said that Alicia and Gwen have never really liked one another as two of them have been in competition for most of their careers. And since Alicia and Miley got super close during last season, the first is desperately trying to give Gwen a hard time and make her change her mind in returning in next season.

But what does Stefani's 40-year-old country singer boyfriend think of all the drama? The source told that Blake and Alicia have already had words about that.

According to insiders, Stefani has already filed complaints with the NBC show's execs about her female competitor. Then he/she added that Gwen Stefani knows for a fact that she has more pull that Alicia does since she has a rock solid relationship with all of the executives on The Voice.

However, there are other reports saying that none of that is true.

Gossip Cop has wanted to set the record straight and according to their source - close to Keys- the report from Radar Online is not true. The singers are not feuding over Gwen's return to the show.

According to the same source, that report is just another fake news story apparently manufactured by the unimaginative reporters. In fact, the readers can find so many of these untrue "Voice" feud tales and they shouldn't take them for granted.
