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.

People magazine reports that Stefani attended George Clooney’s Casamigos Tequila Halloween party in Beverly Hills, California, sporting a cowgirl costume. The 46-year-old mom of three rocked a playful brunette wig, straw hat and colorful cowboy boots. While Us Weekly reports that the No Doubt singer was “riding solo,” Entertainment Tonight has photos of Stefani and Shelton together.

According to the site, “The Voice” co-stars 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, 39, can be seen behind her with his hands hidden underneath a poncho.

A source revealed to ET that the pair left the Casamigos party around 1:30 a.m. holding hands. They reportedly let go after spotting a photographer.

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.
