Gwen Stefani and Blake Shelton’s Halloween party pictures continue to fuel dating rumors. The shots obtained by E!News showed the two engaging in some PDA action over the Halloween weekend.

Stefani and Shelton both attended fellow “The Voice” coach Adam Levine and Maroon 5’s Halloween party in Studio City, California, where they were both spotted being super close to one another, E!News reported. In E!’s exclusive photos, Shelton was photographed holding the “No Doubt” lead singer close to him with his hands on her shoulders. The country singer was also spotted moving his hands down to Stefani’s waist and at one point, even had a hand on her backside.

Sources also told E! that the two “The Voice” judges spent most of the Halloween weekend together. Stefani and Shelton were first seen partying at George Clooney’s Casamigos A-list party. They later reunited at Jared Leto’s private party, where the E! source shared that the recently divorced singers were seen holding hands and left the party together. 

Another E! insider, who also works at “The Voice,” revealed that “there is something going on between them” given their interactions on the set of the singing competition. The source said, "They are definitely flirty on the set and you can see they have fun together... they have spent time together off set. They don't want to label anything or define it, they just really like each other and happen to be going through similar things in their lives.”

The insider further shared how Stefani has already spent time at Shelton’s Hollywood Hills house and that the two “want it to stay under the radar” so that it won’t turn into a “big public thing because who knows what will happen."

Meanwhile, Stefani denied the dating rumors despite the many Halloween party pictures which showed her and Shelton partying together. In an interview during Monday’s “Mornings with Carson Daly” at 97.1 AMP Radio, Stefani told Daly that “[they’re] just trying to have fun.” Apart from denying the dating news, she also talked about her third solo album and her new phase in life which she described as “pretty awesome.”

Stefani announced her separation from Gavin Rossdale in August after 13 years of marriage. Shelton and Miranda Lambert made their divorce plans public in July after being together for four years.
