"The Voice" coaches Blake Shelton and Gwen Stefani, who both recently divorced their spouses, are rumored to be developing a romantic relationship. The two have been "flirting like crazy," according to a show insider.

Shelton divorced his wife Miranda Lambert during the summer, and after the news broke, Stefani then announced her divorce with her husband Gavin Ross. Now, the two are rumored to be interested in each other, according to a source from Hollywood Life.

Although it may seem like a coincidence, the source assured that both "The Voice" coaches have only started their romance after their split from their spouses.

"Blake and Gwen flirt like crazy! They had a great rapport right away, but it didn't really cross over into flirting until they both split from their spouses," the insider revealed.

The source then claimed that the flirting is now getting more and more obvious, saying, "Now, it's full throttle. They have all these inside jokes and we tease Gwen because she laughs waaay too hard at Blake's jokes. She has this little giggle that she does and it's so cute. Blake loves to come up behind her, cover her eyes with his hands and do an Adam Levine impression or something. It just cracks her up."

When news spread that the two are into each other, Shelton was quick to deny the rumors and posted a message on his Twitter. "The stuff I read about myself blows my mind. Shouldn't I get to do all these things since I'm already accused of them? #doublejeopardy," he wrote.

"I literally just got back from FAR northern Quebec chasing caribou and now read about all the crazy stuff I've been doing lately?!! #WTF?!" the country also wrote on Twitter.

Meanwhile, Radar Online claimed that a production source knows that the two are definitely flirting.

"There is definitely something going on with the two of them now. Blake and Gwen are being very flirty both on and off set," the source told the publication. "At first they were just bonding over the fact that they were both going through divorces at the same time."

Their divorces apparently paved the way for the two to be good friends. "That turned into an even closer friendship between them," said the source.

There are still no official statements from Stefani regarding the rumors.
