Johnny Depp and Amber Heard kiss and cuddle at charity event

By Alex Cramer

Six months after their wedding, Hollywood couple Johnny Depp and Amber Heard are definitely still in the honeymoon phase. While at the Music on a Mission event in Los Angeles benefitting MendingKids.org, which the actor told Hello! "was fun," it seems the most action was backstage - where Johnny and Amber were packing on the public displays of affection.

The Pirates of the Caribbean star and his wife were first spotted walking hand in hand and smiling back stage at the Aug. 16 concert fundraiser, where he was scheduled to perform. The newlyweds were sweetly kissing and Amber lovingly wiped some lipstick off of his face just before Johnny took to the stage.

Unlike his showy appearance at Disney’s D23 Expo the previous day, where the actor arrived dressed as Captain Jack Sparrow and entertained the crowd, Johnny didn't said a word as he strapped on a guitar and rocked out to Alice Cooper's classic track “School’s Out” in front of hundreds of fans. Amber stood in the front row and watched her husband adoringly.

Johnny, who dressed in jeans and an oxford shirt topped with a gray vest, was then joined on stage by rock legend Gene Simmons. The KISS bassist challenged the crowd and said that anyone who donated $1,000 at that moment could come up onto the stage and rock out with the band. After a dozen people took him up on his offer, he and Johnny belted out the classic KISS anthem “Rock And Roll All Night” together .

Clearly charmed by the moment, Amber whipped out her phone to film her 52-year-old beau before running on stage to give him a hug when he finished.

Once backstage again, the 29-year-old had her arms wrapped around Johnny as they walked down the hallway smiling and whispering into each other's ears.

"I'm very happy. Marriage hasn't really changed anything between us. We know each other very well and enjoy our time together," Amber recently told Hello!. "What's beautiful is that you're able to learn more about another person, and that deepens your understanding of each other."
