Gwen Stefani and Blake Shelton took a little time to themselves after the chaotic holiday season. The rumored couple were spotted touring different wineries in Southern California together and, according to onlookers, they were "sweet and delightful."

E! Online reports that the NBC "The Voice" co-hosts jetted to Santa Barbara, California, for a little wine tasting. Sources tell the publication they "seemed very happy together" as they sipped different wines and toured the vineyards. They were reportedly somewhat affectionate, though onlookers called their public displays of affection, or PDA, "appropriate." A fan-run Instagram account shared a photo of Shelton, 39, during his visit to the winery, suggesting that perhaps the trip was a part of a "romantic getaway," according to E!. 

As was previously reported, wineries weren't the only thing on the might-be couple's agenda. Stefani, 46, and Shelton joined a few friends to attend the Green Bay Packers vs. Arizona Cardinals game at the University of Phoenix Stadium in Glendale, Arizona, Sunday. The "Used To Love You" singer shared a photo of herself and the unnamed friends on their way to the game. 

The wine tasting trip comes just days after Stefani and Shelton celebrated Christmas. The recent divorcees were spotted spending time together in Oklahoma over the weekend. Neither posted photos or tweeted about their time spent together, but Entertainment Tonight (ET) reported that Atwoods Ranch and Home shared a photo on Twitter of them outside the store.
