While Gwen Stefani was dressed as a sexy zombie cowgirl, rumored beau Blake Shelton did not even seem to have made an effort for George Clooney's Casamigos Tequila Halloween bash last Friday.

"Blake - who has been linked to Gwen since her recent marriage split - was also at the star-studded bash, hiding underneath a poncho and huge fake beard," Daily Mail said.

Gwen Stefani was garbed in a denim mini-dress, knee-high boots, yellow stockings and cowboy hat. Half of her face was also covered in fake blood.

The two "The Voice" judges were linked to each other after Gwen Stefani filed for divorce with rocker husband Gavin Rossdale and Blake Shelton split from wife Miranda Lambert.

According to multiple rumors, Gwen Stefani and Blake Shelton are "flirting openly" on the set of "The Voice" and their chemistry is unmistakable to those around them.

Blake Shelton already earlier addressed the rumors about dating Gwen Stefani as he tweeted, "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."

Gwen Stefani just shrugged off the rumors about the former No Doubt singer reportedly dating Blake Shelton.

In an interview with Entertainment Tonight at the sidelines of MasterCard Priceless Surprises, she said that there's only good vibes on "The Voice" show even with all their troubles outside it.

"It seems like the cowboy is really happy on the show," Gwen Stefani said. "We're all having so much fun on that show. Everybody is in such a good place."

When she was asked about the rumor about dating Blake Shelton, Gwen Stefani just laughed and feigned surprise, "Have you read the news?"

The "Spiderwebs" hitmaker will not be coming back to "The Voice" next season as Christina Aguilera will reclaim her chair, joining Blake Shelton, Pharrell and Adam Levine.
