Gwen Stefani and husband Gavin Rossdale do not seem to get enough of each other. The couple was seen sharing a passionate kiss onstage when they performed at the 23rd Annual KROQ 'Almost Acoustic Christmas' at Gibson Amphitheater, Los Angeles, according to Gossip Cop. The couple met 17 years ago at the same show, so we guess they got a bit nostalgic during the performance.

Rossdale played the "Glycerin" song and started off alone but was later joined by Stefani when she walked on to the stage and the audience could not  control their excitement. Not just the audience, even Rossdale seemed pleased and excited about Stefani's sudden appearance.

"She actually asked me about this and I was so surprised, I didn't say anything for two days," he told the Rolling Stone magazine. "She said, 'Maybe we should do a song together.' And I couldn't answer her."

The couple later decided to perform, "Glycerin." "I thought it would be so powerful, the two of us onstage like that, that's what we went for," Rossdale said. And he believes that the song sounded "so much better" with Stefani.

Though there have been repeated rumors about the musical couple calling it quits, the duo through this onstage reunion has put the speculations to rest.

Stefani and Rossdale seemed to be unperturbed by the rumors of their divorce as they were spotted enjoying a day out with their children, Kingston and Zuma at the Beverly Hills Park, Dec. 8 by The Daily Mail. While Rossdale was dressed warm and casual in a pair of jeans and jacket, Kingston and Zuma were seen in trendy costumes.

Kingston was dressed up as a power ranger and Zuma was a Spiderman. The family was accompanied by the nanny. Undoubtedly everyone was well dressed; but it was Stefani who stole the limelight. Stefani looked stunning in a mini dress, a woolen coat and leather boots. The 43-year-old accessorized with an elegant fedora hat and vintage sunglasses.
