Blake Shelton and Gwen Stefani both went through divorces this summer, and they've reportedly turned to each other for support, the Daily Mail reported. But their friendship is quickly turning into romance as the two spark dating rumors on the set of NBC's "The Voice."

The co-judges reportedly are in the "early stages" of a budding romance, an insider told Life & Style magazine, as reported by the Daily Mail. The 39-year-old country star and 45-year-old No Doubt rocker are attempting to keep their relationship on "on the down-low."

"The chemistry between them is off the charts. Everyone on set sees that Blake and Gwen are falling for one another," the source said, according to the Daily Mail.

Shelton announced his split from country singer Miranda Lambert in a joint statement in July, as previously reported by HNGN, after only four years of marriage.

Stefani and her longtime love, Bush rocker Gavin Rossdale, also announced their split in a joint statement, as previously reported by HNGN. They filed for divorce in August after 13 years and three children together.

The co-judges are reportedly bonding over their recent divorces, but even though they're both still healing from their failed marriages, they're reportedly finding ways to flirt with each other while on set.

"Now that they're both single, everything has changed," the source claimed. "The whole set is buzzing."
