Blake Shelton and Gwen Stefani’s dating rumors have been heating up with a new report claiming that Adam Levine is teasing the two about a possible romance. Shelton and Stefani fueled the gossip mill after they were seen flirting with each other on the sets of “The Voice.”

“Blake and Gwen’s relationship is definitely water cooler talk on the set of 'The Voice',” a source told Hollywood Life. “Everyone wants to see them happy and it just seems like perfect timing for them to become more than friends. Their two divorces are not really talked about openly -- by anyone other than Adam. He loves to tease Blake and Gwen about a possible romance. He jokes that they are both single now so they should just go ahead and do it. He can’t help himself.

“Adam and Blake are like brothers so anytime they can give the other one a hard time they go for it. It’s all in good fun though as Adam is completely supportive of both Blake and Gwen and the difficult time they have been going through in their personal lives. They are definitely a big loving family,” the source added.

Stefani and Shelton came close to each other after the former divorced English musician Gavin Rossdale and the “Sangria” singer divorced country singer Miranda Lambert.

According to some sources, Shelton has been keeping Stefani happy and making her laugh at “The Voice” sets, despite his divorce woes.

“She can’t believe how blessed she is to have been offered this job on 'The Voice' where she gets to be around amazing people like him, Adam and Pharrell [Williams],” another source told Hollywood Life. “She loves them all like brothers but it’s Blake who really helps keep her mind off her split with Gavin. Despite his own marriage trouble, Blake is always smiling and keeping things light on set. Any time Gwen feels like crying, Blake is there cracking her up. He’s helping through her break up with belly laughs!”

Meanwhile, Luke Wade, who was part of ‘The Voice’ Season 9, spoke out about Stefani and Shelton’s possible relationship.

“I think just having known the two of them I could kinda see that,” Wade told Hollywood Life. “She is so sweet and Blake is the eternal charmer, so I could easily see how it could happen when you are working together doing something that you both love.”

Wade added that Stefani and Shelton’s respective marital problems were, in fact, helping them confide in each other.

“Gwen and Blake are getting through this together by making each other laugh. Their friendship has blossomed through both their marital issues that they’re dealing with. They have confided in each other in a way they really can’t with others because they both know how it feels being a celeb and going through stuff like this. They are a great support system for each other,” Wade reportedly said.
