While appearing on Jimmy Kimmel Live! on Thursday, March 24, the No Doubt alum showed up without the sparking diamond ring on her wedding finger!
After the late-night host pointed out the missing bling, Stefani, 52, explained it was just a mindless mistake.
"I forgot to wear my ring," she said during her Thursday night appearance. "It's like, the first time! I thought, 'OK I'm going to put it in the jewelry cleaner so Jimmy sees how sparkly and amazing my ring is,' and then hello, empty finger."
"I'm so embarassed!" she squealed, while stating: "I'm sorry, Blakey" to her country singer husband.
Fans of the newlyweds could rest assured after Stefani confirmed there has been no trouble in paradise, adding: "I love my husband, and I love being married to him. It's just the greatest thing that's ever happened to me."

Stefani and Shelton first met on the set of The Voice, while they were both going through divorces at the time from exes Gavin Rossdale and Miranda Lambert, respectively.
Their whirlwind romance heat up quickly, until the country crooner finally got down on one knee in October 2020 before having their dream wedding in July 2021.
Shelton, 45, has previously expressed his pride over his gorgeous blonde wife, and it's safe to say Stefani feels the same way despite the recent ring blunder.
As OK! reported, Shelton opened up about wanting to share their love story with the world, saying "I'm really proud of it."
"To me, a marriage, a ceremony, you're not keeping it in private when you get married to somebody — you're announcing to the world, 'Hey this is my wife, just so everybody knows.' That's why we wear these rings," the "God Gave Me You" singer said at the time.
