Season 9 of The Voice will premiere in just ten days, and a source close to production for NBC's hit singing competition show. Radaronline reported that behind the scene chemistry between the two recently divorced judges is getting hotter each day. According to the on-set sources, both judges are extremely flirtatious on and off the sets.

Both judges have been seen leaving sets together more than often and Blake had invited Gwen to the bar with him after taping too. Both judges had been going through divorce nearly at the same time and have been seen getting cozy on the sets of The Voice. While Blake Shelton divorced singer Miranda Lambert and Gwen had separated from English musician and actor Gavin Rossdale last month.

Music Times reported Blake to be having fun with dating gossips doing rounds and even tweeted calling the possible dating life "awesome." He also tweeted that he had to check internet to check who he is dating these days. Gossip Cop was the first site to debunk any such rumors stating Shelton's representative has made a statement that any dating rumors are totally untrue.

Miranda Lambert, the 31-year old singer, seemed to be too upset with Blake and Gwen's dating rumors. An insider said that Shelton and Stefani rumored relationship was Lambert's "worst nightmare." Lambert and Shelton divorced in late July after four years of marriage, said International Business Times.

The insider also shared that Blake likes that Gwen has children. He had wanted children while Miranda never wanted children. Gwen is doting mother which makes Shelton interested in her.

Gwen and Miranda were friendly before Gwen was rumored to be hooked up with Shelton. Miranda feels any relationship with Gwen will dry up her chances of being with Shelton again.
