Gwen Stefani and Blake Shelton may have been married secretly after the No Doubt frontwoman was seen wearing a new diamond wedding ring.

In the snaps obtained by The Post, the 51-year-old singer had another band next to her engagement ring. This sparked wedding rumors. Did the two tie the knot without anyone knowing?

Stefani recently posted a snap of herself enjoying a drink and holding a gift with the words, "She's getting married." The ring wasn't in the photograph but she was later spotted wearing it during a trip with her soon-to-be-husband and her 7-year-old son, Apollo, in Santa Monica, California.

The couple have only recently returned from Shelton's Oklahoma ranch where a source said he built a chapel where they planned to exchange vows, Page Six reported.

When will the wedding take place?

It was "most likely" to happen this year - but it now looks like it already has.

Shelton proposed to Stefani in October with a six- to nine-carat diamond ring.

The mother-of-three said "yes" and the news was they would wed soon.

The "Hollaback Girl" hit maker shared photographs and video of her bridal shower with friends and family at a restaurant celebrating the engagement.

"I got kidnapped by my family to celebrate...I'm getting married!" she captioned the post.

It also features gifts and her parents' wedding invitations. In an interview with Today, Shelton revealed he and Stefani planned to marry "hopefully this summer," E! News said.

"I think in a romantic way when you fall in love so hard and so unexpectedly and so late in life you think, 'I want to marry you, like now!'" Stefani said.

She said their first reaction was to get married immediately.

However, as the years went by, she thought it didn't need to happen so soon. Before the two made their romance public in late 2015, Shelton had ended his four-year marriage with Miranda Lambert.

Stefani, on the other hand, was also proceeding with her own divorce from Gavin Rossdale, who fathered her three children, Kingston, Zuma and Apollo.
