Gwen Stefani and Blake Shelton may have delivered a Halloween treat to fans pushing for a romance between “The Voice” judges. The two recently single singers were photographed leaving a Halloween party together Saturday night, and were allegedly spotted holding hands.

The first stop of the night for Gwen Stefani and Blake Shelton was George Clooney‘s Casamigos Halloween Party. The two arrived and left separately, ET Online reports, while she donned a bloody cowgirl outfit and he wore a Mexican poncho, a flannel and a trucker hat.

According to the site, Gwen Stefani and Blake Shelton arrived separately at the party, but a photograph of them leaving the event shows them in the same vehicle.

Although the paparazzi caught them together, the two were not engaged in any PDA. In fact, photos show Stefani with arm arms crossed tightly over her chest. Shelton can be seen behind her with his hands hidden underneath a poncho.

They spent about 40 minutes and “looked happy” together and were even holding hands when leaving. However, she guided him outside and they let go of each other’s hands the minute they saw a photographer. They then got into a car together to leave — she took the back seat while he sat in front of her.

The Halloween bash has once again sparked rumors that Stefani and Shelton are an item. Speculation about their dating life has been a hot topic ever since the two filed for divorce. Shelton and country star Miranda Lambert, who were married for four years, announced on July 20 that they were divorcing. Meanwhile, Stefani and husband Gavin Rossdale filed for divorce in August after 13 years of marriage.

Ever since Blake’s split from wife Miranda Lambert along with Gwen’s divorce from longtime husband, Gavin Rossdale, the two have been spending a lot of time together.

HollywoodLife previously reported that Gwen Stefani and Blake Shelton spend time talking about everything, except their exes.

“Blake loves talking to Gwen and talking to her about music and everything else, except divorce talk,” a source told the site. “Blake doesn’t like talking about divorce because it gets him to think about his divorce, and he wants to move forward instead of backwards.”
