Blake Shelton wants to make his former wife Miranda Lambert jealous by flirting with Gwen Stefani, Hollywood Life reported. The news comes amid reports that Shelton and Stefani, who have been speculated of being romantically involved, are just friends.

“It’s not romantic, but that doesn’t mean they can’t participate in some good natured flirting,” a source told Hollywood Life. “Blake can’t help himself, he’s a natural flirt and Gwen is adorable. Part of him hopes that seeing him looking so fit and working so close with a knock out like Gwen makes Miranda jealous.”

Shelton and Stefani sparked dating rumors after they were seen flirting with each other on the sets of “The Voice.”

“Blake and Gwen are having a great time working on 'The Voice',” the source reportedly said. “Blake always had fun before but having smiley Gwen on has really added to the vibe on set. She’s much more relaxed this season and full of energy. Blake is a comedian but Gwen is also funny in her own way and makes him laugh.”

Despite the rumors being widely debunked, gossip about a possible romance persists. According to Life & Style, the two have been planning to move in together. However, this report was refuted by Gossip Cop.

Shelton recently spoke out about his divorce with Lambert revealing that the process didn't take much time.

"We knew if rumblings and rumors started coming out, they would just be that, because by the time anybody knew anything it was over. It was done," Shelton said, in an interview on "The Bobby Bones Show" earlier this week. "Our whole thing was, we are going to be cool about this, it is what it is. We're buddies."

Shelton, 39, and Lambert, 31, who were married for four years, went public about their divorce in late July. Since the split, the "Sangria" singer has been showing off a much thinner frame. He opened up about his weight loss in an interview Wednesday saying his skinnier physique is the result of what he calls the "divorce diet."

Shelton’s divorce woes were reportedly cited as a reason for his close relationship with Stefani, as the two have been going through the same phase.

Stefani filed for divorce from Gavin Rossdale in August, ending their 13-year marriage.

Luke Wade, who was part of ‘The Voice’ Season 9, recently said that Stefani and Shelton’s respective marital problems were, in fact, helping them confide in each other.
