Gwen Stefani embraces her No Doubt roots as she goes grocery shopping rocking plaid top

She rose to fame as a member of the band No Doubt.

And Gwen Stefani embraced her ska punk days while grocery shopping in Los Angeles on Monday.

The 51-year-old singer covered up her age-defying figure in ripped jeans, a striking plaid shirt, and Vans sneakers.

Gwen’s cropped jeans were cuffed at the bottom and ripped in several spots along her legs and thighs.

She held up the high-waisted jeans with a thick blue-and-white patterned belt, which contrasted with her green, blue and white plaid button-up shirt. 

The 5ft6in singer had the long-sleeve item buttoned all the way to the top and kept up the low-key look with slip-on red-and-white checker sneakers.

She wore striking crimson lipstick that contrasted with her pale skin and platinum blonde locks, which were tied back in a high ponytail.

Although many businesses in LA now allow fully vaccinated customers to shop maskless, Gwen opted to put on a disposable mask before rolling her cart into the store.

Missing from her trip to the store was her fiancé Blake Shelton, 45, as well as the three sons she shares with her ex-husband Gavin Rossdale: Kingston, 15, Zuma, 12, and Apollo, seven.

The Hollaback Girl singer appeared to shade her ex-husband, the lead singer of Bush, with a Father’s Day post last week that focused only on Blake without a mention of Gavin.

The Voice coach and country superstar was seen bonding with her boys in several sweet photos, while their biological father was conspicuously absent.

‘Happy father’s day to the most generous patient loving funny guy i know — we love u so much,’ she wrote while tagging Blake. 

Earlier this month, the songstress shut down rumors that they had secretly married in a sweet Instagram post celebrating her fiancé’s birthday.

‘Celebrating my besties b day today love u,’ she wrote, while including the hashtag, ‘#fiance.’

Gwen sparked rumors of secret nuptials earlier this month when she was spotted out wearing a diamond-encrusted band along with her regular engagement ring.

Even if there hasn’t been a wedding yet, Gwen is reportedly ‘ecstatic’ at the thought of the approaching ceremony, a source told People earlier in June, though she and Blake are waiting until it’s safe to have all the guests they want. 

‘Ever since they got engaged, they have both been adamant that no wedding will happen until it’s safe for family and friends to attend. Gwen expressed early on that she really wanted a summer wedding,’ the source said. ‘She was upset earlier this year when it seemed to be no end in sight for the pandemic. She slowly started planning the wedding this spring though.’

She and Blake are reportedly eyeing a wedding in the new few months.

‘They are both ecstatic that it can finally happen. They are getting married this summer. Gwen’s boys will be very involved,’ they continued. ‘Blake is a great extra dad and very close with the boys.’
