Gwen Stefani, Blake Shelton Dating: 'The Voice' Judges Spotted Engaging In Major PDA [Photo]

Despite denying that they are dating, "The Voice" judges Gwen Stefani and Blake Shelton were recently spotted getting cozy together. E! Online reported that not only did the two spend the holiday weekend with each other, Gwen and Blake were heavy on the PDA, too.

The news outlet published exclusive photos of the two stars, which were apparently taken during a Halloween party hosted by Adam Levine. In it, Blake was seen resting his arms around Glen's waist and the two were talking to each other, seemingly oblivious to the crowd around them.

A source also confirmed to E! that Gwen and Blake were also at George Clooney's Halloween party, where they arrived using different cars. While they started out greeting guests at the star-studded affair separately, later that night it looked like Gwen and Blake became comfortable around each other in the crowd, according to Entertainment Tonight.

Hollywood Life reported that at Clooney's party, Gwen and Blake were seen "holding hands," but they let go of these as soon as a photographer was nearby. They also left in the same car, but Gwen sat at the back. The couple were described as "looking happy" together.

Gwen and Blake have always maintained that they are just friends despite rumors of their romance. Their relationship allegedly came at a most convenient time, when the two announced their divorce from their exes, Gavin Rossdale and Miranda Lambert, almost at the same time. They supposedly bonded over the fact that they're going through a similar experience, as previously reported on Parent Herald, and got closer while working on "The Voice."

According to Gwen, she's just enjoying her life the way it is. "My life feels so extreme right now," the singer told People. "The Voice is so fun ... this season is crazier because I feel like I know everybody so well and also because my life is crazy. I mean, my life basically blew up in my face and so now I'm like, in this new life and it's pretty awesome, I have to say." She also told the news outlet that she and Blake are "just trying to have fun."

Radar Online reported that the two have been on secret dates. "Their dates have consisted of hanging out at Gwen's Beverly Hills mansion whenever the boys are with Gavin," a source told the news outlet. "Blake gives Gwen tons of attention, and is constantly complimenting her. Gwen is impressed with Blake being such a gentleman with her. It's definitely been a huge ego boost after the hell she went through with Gavin."
