Gwen Stefani and Blake Shelton step out together to enjoy friend's wedding (photos)

Gwen Stefani and Blake Shelton danced at a wedding to 'Hollaback Girl'

Fans who have been eagerly waiting for Gwen Stefani and Blake Shelton to announce their engagement can now enjoy photos of the couple dancing at a wedding - but not their own.

Stefani, 48, posted photos and videos on Twitter of the couple enjoying themselves on the 2nd of May as they celebrated at an unidentified close friend's wedding.

The No Doubt vocalist wore a shimmering black and white dress paired with elegant knee-high boots and had her blond hair pulled up into a high ponytail.

Shelton looked perfectly groomed and debonnaire as always in a tailored black suit and with a white boutonnière indicating he might be serving as a groom's man.

"You know what? I love weddings, the kids love him. We love him (Blake)."

Stefani, 48, filmed the bride and groom's entrance into the wedding reception, and captioned her clip "worst filming ever."

While Shelton posed for photos with the wedding party, Stefani played cameraman and took a cute selfie.

The night ended with Stefani being pulled on to the dance floor to dance to her own hit "Hollaback Girl."

The couple, who have been together since November 2015, has hinted that tying the knot may be in their future plans.

Stefani admitted on The Ellen DeGeneres Show that marriage to Shelton 'crosses her mind,' but the couple has yet to announce the engagement, let alone the wedding.

Both have been married before, and though Shelton is childless, Stefani shares two children, Zuma and Apollo, with ex-husband, Gavin Rossadale.
