The couple, who have been dating for nearly a year, were caught sneaking a secret smooch outside of Joan’s on Third in Studio City, California.
Stefani, 47, was rocking a long cameo jacket, black top and patched, embroidered jeans. She kept her blonde locks back in a a high ponytail, accessorizing her look with suede boots and a pair of killer shades.
Shelton, 40, looked relaxed in an orange-and-blue checkered shirt, jeans, and trucker-hat combo. The country crooner showed off his roots in a pair of cowboy boots.
Shelton and Stefani went public with their romance around the Halloween holiday last year, after meeting on The Voice — where they both worked as coaches. Both stars ended long-term relationships that year, with Shelton and Miranda Lambert divorcing in July and Stefani and husband Gavin Rossdale announcing their split several weeks later.
The mother of three recently told PEOPLE that life couldn’t be better.

“I’m the happiest I’ve ever been,” she gushed about her boyfriend and “Go Ahead and Break My Heart” duet partner.
The star celebrated her 47th birthday earlier this month and is the first to admit it’s been a life-changing year for her.
The two are also grateful for their fans, who quickly embraced them as a couple.
“We feel it,” she said of the fan support. “I was saying yesterday to somebody, I really feel the love, you know what I mean? It’s hard to put into words, but it’s a really cool thing to have that.”
