Since filing for divorce from Miranda Lambert in late July after four years of marriage, reports swirled Shelton had "the hots" forThe Voice's Season 9 key advisor Rihanna, and now, he allegedly initiated a "hot new romance" with Stefani.
Newly-single Shelton and Stefani -- who also filed for divorce from Gavin Rossdale in August after 13 years of marriage -- have a blossoming romance and flirtatious dynamic that have people onThe Voice set buzzing, Life & Style reported, according to the Daily Mail.
An insider told Life & Style the Oklahoma native and California girl are trying to keep things "on the down-low" although they constantly compliment one another on The Voice.
"But it's not happening partly because they're all over each other," said in the insider. "The chemistry between them is off the charts. Everyone on set sees that Blake and Gwen are falling for one another... Blake and Gwen have a lot more in common than either of them thought."
"Now that they're both single, everything has changed," a source told the magazine.
However, Shelton, 39, took to Twitter on Thursday to seemingly crack a joke about all the dating hype in the media.
"Getting ready this morning to go put in my deer plots and looked at Twitter... Damn my dating life is awesome!! Let me know what happens...," the country singer tweeted.
Despite claims Shelton and Stefani, 45, bonded over the pain of cheating rumors in their previous marriages, Gossip Cop reported it's all "completely untrue" and they're definitely not dating.
Life & Style sources recently claimed Shelton admires Stefani's talent and business sense as well as the fact she's a doting mom to sons Kingston, 9, Zuma, 7, and Apollo, 18 months. The rock star's nurturing nature is reportedly "enticing" to Shelton because he yearns to be a father.
"When they're not together, Blake has been calling her, too. He's even given her some small gifts. He sees Gwen as the ultimate woman, and she has been reveling in the attention," a friend told the magazine, adding that Lambert has heard about their relationship and is "really upset."
