Blake Shelton, Gwen Stefani 'The Voice' Flirting? Miranda Lambert/Gavin Rossdale Split Comfort

Both Blake Shelton and Gwen Stefani are now single. So, is a flirtatious romance blossoming on "The Voice" set?

The No Doubt pop sensation filed for divorce from longtime hubby Gavin Rossdale in August 2015. Shelton went through a bitter break-up with country music sweetheart Miranda Lambert just a few weeks prior. Perhaps 46-year-old Stefani and the 39-year-old "Sangria" crooner aren't hooking up (yet), but they are bonding over shared heartbreak:

"The beauty of it is that you can tell she really trusts him," an alleged insider tells HollywoodLife.com. "He doesn't have this predatory energy about him like a lot of guys, and because they started as friends, her guard is down."  

How does "Gwake" sound - a true match made in Hollywood? Obviously there's an emotional connection between the two, but will sparks start flying soon? Hey, it coul happen!

"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," another snitch reveals. "Now, it's full throttle. They have all these inside jokes and we tease Gwen because she laughs way 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." 

Should the Maroon 5 rocker play ultimate matchmaker?

Battles on the hit singing competition (season 9) are getting intense, so perhaps Stefani and Shelton should turn up the heat (behind the scenes), too! Sound-off in the comments section below, MstarsNews readers. Would this be the perfect "revenge" rebound?

But who knows - Shelton recently mocked such relationship rumors on Twitter:

@blakeshelton: "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?!"

@blakeshelton: "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."

Friendly support doesn't necessarily mean sexual chemistry - stay tuned...
