Gwen Stefani Lights Up Los Angeles Show With Surprise Guests Blake Shelton and Son Kingston

The 47-year-old singer got the crowd feeling 'hella good' on Saturday night.

Gwen Stefani's latest performance was literally lit -- and hella hype!

The 47-year-old singer rocked the house at The Forum on Saturday, performing to a sold-out crowd during night one of two stops in Los Angeles as part of her This Is What the Truth Feels Like tour.

"Los Angeles!" the Orange County native, who opened her two-hour set with "Red Flag," exclaimed onstage at the iconic venue. "Stop it. Let's take a moment here. This right now is a miracle, OK? For me. I cannot believe you're here, I'm seeing you right now in L.A., and this is happening."

While all eyes were glued to the platinum blond's edgy-meets-glitzy costumes and impeccable abs as she danced and sang to hits like "Baby Don't Lie," 'Misery," "What You Waiting For?" and "Hollback Girl," fans couldn't keep their cool over her guests of honor.

The most memorable moment was when her boyfriend of a year, Blake Shelton, took the stage to surprise fans. The crowd erupted with cheer when they saw the 40-year-old country crooner appear with his guitar in-hand and a beaming smile on his face.


The two performed their romantic duet, "Go Ahead and Break My Heart," off Shelton's If I'm Honest album, gazing into each other's eyes from start to finish, much like they did when they performed it live for the very first time on The Voice back in May.

At one point, Stefani's eldest son, 10-year-old Kingston, came out to watch his mama in action from the side of the stage. As adoring fans chanted "Gwen!" over and over following her powerful performance of "Truth," you could see Kingston on the side cheering for more, lifting his arms up and jumping up and down in awe of the entire venue being lit up by cell phone lights.

Later, Stefani even called her little man over to join her for final bows!


But that's not all. Opener Eve helped Stefani take the rad crowd back to the early 2000s, performing their popular hits, "Rich Girl" and "Let Me Blow Ya Mind."

Though the audience was extremely hyped during the entire concert, they were extra energetic when Stefani belted out one of her most iconic No Doubt jams, "Hella Good." And yes, the crowd did keep on dancing!

Aside from all the fun, there were plenty of emotional moments, too. Talking about her past year -- in which she divorced Gavin Rossdale -- Stefani candidly told fans, "I'd be dead without you guys," before going into an emotional rendition of "I Used to Love You." "Thank you for letting me share that with you," she said.

"I'm actually scared of Los Angeles right now," she joked, seemingly shading the Bush frontman.

The ex bashing didn’t stop there, however. After performing "Baby Don't Lie," Stefani hilariously said, "You know, I really hate liars. I hate liars!"

Clearly, it was all in good fun, and well-received by her fans, like Marissa Estle, who drove all the way from Sacramento to attend the show. Little did she know she'd be pulled onstage by the rock goddess, who signed her L.A.M.B.-inspired tattoo and sealed it with a kiss! Naturally, Estle immediately got Stefani's signature and red lip print permanently inked.

So rad!

The evening was clearly a memorable night for Stefani, who noted many times onstage that she hasn't "toured in seven years," her last being The Sweet Escape in 2007. "I feel so grateful," she gushed. "Thank you guys for listening to this record, and thank you God."
