No Doubt lead singer Gwen Stefani and singer Blake Shelton may be more than “just friends,” as a series of paparazzi images show.

The two were reportedly seen together throughout the Halloween weekend at a Maroon 5-hosted party, where they were seen in a rather romantic embrace. Another source said that the two were seen holding hands at another party hosted by Jared Leto.

Stefani and Shelton were seen leaving the place together. An insider who works for the two The Voice judges said that they really like each other. “They are definitely flirty on the set and you can see they have fun together,” the source added. While the source mentioned that there is really something going on between the two stars, they “don’t want to label anything or define it.”

The alleged romance between the two judges may not be that surprising, considering they have been close in the last two seasons of The Voice.

However, it is worth noting that both celebrities have gone through divorces this year, and just recently, too. Shelton, 39, initially filed for divorce from his wife of four years, Miranda Lambert in July, while Gwen Stefani, 46, divorced her husband, Gavin Rossdale, in August after 13 years of marriage.

When asked personally about things going on with her and Blake, Stefani did not admit nor deny it.

Gwen said in an interview with Ryan Seacrest, “to be super honest, it is kind of crazy that we both went through the same thing at the same time.”

However, she did admit to the host that she finds Blake “hot.”

“I think he’s hot, don’t you?” asked Gwen Stefani, who is currently promoting her new album, Used to Love You.

Still, she did not disclose any more details. The two first worked together on The Voice in May of last year.
