Blake Shelton and Gwen Stefani, who are single and fresh out of their respective marriages after divorcing their spouses at the same time, have sparked rumours of budding new romance.

According to the latest reports, the buzz comes from the sets of "The Voice" where the 39-year-old country singer and 45-year-old rockstar have been seen flirting with each other.

Despite of the pair's effort to keep it low key, their flirtatious behaviour has sent out clear signals about a budding romance, reported The Daily Mail (via Life & Style). "They're trying to keep it on the down-low, but it's not happening partly because they're all over each other. The chemistry between them is off the charts. Everyone on set sees that Blake and Gwen are falling for one another," a source said.

As you may already know that Blake Shelton is fresh out of his high-profile marriage with Miranda Lambert, whereas Gwen Stefani called it quits with long-term husband Gavin Rossdale.

Both Blake and Gwen have gradually come close and are now completely into each other, reported Radar Online. "They're really into each other ... let's face it, they were both unhappily married when they met. Now their divorce proceedings are something they can talk about and commiserate over," a source said.

Apparently, it was Miranda Lambert's ex who initiated the romance. "The Oklahoma native was the initiator from the beginning as he used to flirt with all the cute girls, but not anymore. All that's changed since they both got divorced," the source explained.

The report also stated that though the two singers seem like they are complete opposites, they have a lot more in common. "Blake and Gwen have a lot more in common than either of them thought. Miranda never wanted to have children with Blake, and he wanted kids very badly. Gwen is a doting mom who comes with children; that is enticing to him," an insider revealed.

Amidst these wild Gwen Stefani dating speculations, Blake has sparked another rumour by hinting that he may end up hooking with the "Diamonds" singer Rihanna. In an interview with Access Hollywood on 8 September, 2015, Blake joked: "I was amazed by Rihanna. She is so funny and she's crazy about me. We'll probably end up hooking up at some point. I'm just saying."

And interestingly, he added: "I see a collaboration — maybe not musically. You know what I'm saying?"

Now we wonder, what Miranda Lambert is thinking after hearing these rumours revolving around Blake Shelton, Gwen Stefani and Rihanna.
