Speculation and gossip about the couple went into overdrive this summer (15) after Shelton split from his wife Miranda Lambert shortly before Stefani ended her 13-year marriage to Gavin Rossdale, but aside from joking about the rumours, neither has commented.
When the No Doubt star and country singer Shelton were spotted getting cozy at back-to-back Halloween parties over the weekend, news outlets started flooding the unlikely pair's publicists for answers.
Now Stefani's representative has told Us Weekly magazine, "Gwen and Blake are longtime friends who have very recently started dating." There has been no further comment.
Gwen and Blake have been flirting with each other on the set of U.S. talent show The Voice for weeks, and sources claim Stefani will accompany the 39-year-old singer to the Country Music Awards in Nashville, Tennessee on Wednesday night (04Nov15).
The confirmation comes a day after Hella Good singer Gwen briefly opened up about her feelings for Blake in an interview with U.S. DJ Ryan Seacrest, telling him, " I do think he's hot, don’t you?"
Shelton and Lambert, who will also be at the CMAs on Wednesday, divorced suddenly in July (15) after four years of marriage.
Blake previously admitted the ceremony is sure to be uncomfortable, and he's bracing himself to be the butt of pals and awards co-hosts Brad Paisley and Carrie Underwood's divorce jokes.
"There's gotta be a (joke) about me and Miranda," he recently told U.S. late night host Seth Meyers. "Brad Paisley is not doing his job if he doesn't look down there and go, 'Haha!' He's gotta do it! You have to address the elephant in the room."
