Gwen Stefani and Blake Shelton have been flirting with each other on the set of NBC's "The Voice," reported Us Weekly. The co-stars have a ton of chemistry that's been captured on camera, which only adds fuel to the rumors that the two are dating, but now sources for Shelton are giving out conflicting reports.

"They're a real thing," a source from Shelton's camp told Us Weekly of his alleged relationship with Stefani. The source also goes on to say that Shelton is smitten with the 46-year-old No Doubt rocker and mom of three, adding: "He thinks she's a badass!"

But another source close to the 39-year-old country star said the two recently divorced co-stars are just having fun together while on "The Voice."

"It's total bulls--t," the source told People. "There's nothing there. They're nothing more than friends."

Both Shelton and Stefani announced their respective divorces — Shelton from country singer Miranda Lambert and Stefani from Bush front man Gavin Rossdale — over the summer, HNGN previously reported. The newly single stars first sparked dating rumors in September.

In a video compiled of clips from various examples of Shelton and Stefani's flirtatious exchanges, edited by Us Weekly, the two do seem to have playful stage banter.

"Pharrell [Williams] is so cute, it's distracting," said Stefani in the clip, "and then there's Blake who, again, is very..."

"Sasquatch?" he jokingly chimed in.

"Handsome," she finished.
