Gwen Stefani Steps Out in Bizarre Outfit Following Nashville Trip With Blake Shelton -- See the Pic!

Gwen Stefani's edgy sense of style is no surprise, but her most recent outfit is B-A-N-A-N-A-S.

The 46-year-old singer was spotted in West Hollywood, California, on Saturday, rocking a unique get-up that consisted of a sheer black tank top over a bright blue bra, which was tucked into her low-rise distressed jeans in an odd fashion that made it look like she was wearing a bodysuit. She accessorized the quirky ensemble with a faux fur jacket, neon orange kicks and leopard-print sunglasses.

The "Used to Love You" singer was photographed in the outfit as she stepped out to get her nails done and later visit a pet store to look at exotic birds. Stefani and her two older sons, 9-year-old Kingston and 7-year-old Zuma, recently took home a pet parakeet over Halloween weekend, so perhaps they were looking to buy Tigarlily a friend? 

The No Doubt rocker is back in Los Angeles after spending some time with her new boyfriend, Blake Shelton, in Nashville, Tennessee. Stefani -- who confirmed her relationship with the country crooner on Wednesday -- was in the Southern city to support Shelton as he performed at the Country Music Awards. An insider tells ET that they "looked happy" as they were spotted holding hands in public while leaving the Warner Music Group CMA after party.

On Friday, Stefani's ex-husband, Gavin Rossdale, was seen grabbing coffee in Studio City, California, and, despite the news of Stefani's new relationship, the Bush frontman was still sporting his wedding band.

As ET previously reported, Rossdale announced his divorce from Stefani in August. The couple, who were married for 13 years, have joint custody of their three kids together -- Kingston, Zuma and 1-year-old Apollo -- and are still legally married. The two have settled their divorce but are still waiting for a judge to officially sign off on it.

Stefani's new relationship comes only four months after she and Rossdale called off their marriage. Shelton also went through the same situation this summer, announcing his divorce from country singer Miranda Lambert in July.
