“He came to us five weeks ago, and we realized that he has a cute little voice – a good little voice – and a passion and he said, ‘You know, why don't I do a Christmas song? Why don't I, you know, do a Christmas song and give the-the funds to a charity of his choice?’ And we said, ‘Great. Great idea.’”

They collaborated with family friend, Scooter Braun, the famed manager of Justin Bieber, and together they made the song “If Everyday Was Christmas.”

Calling himself and wife, Victoria Beckham, “proud parents,” the retired soccer pro didn’t seem entirely optimistic when asked about a potential collaboration between his son and the former Spice Girl.

“Oh, I don't know about that. You'd have to ask Victoria,” he told ET. “I doubt, I doubt that. I'd love to see it, but I'm not sure it's gonna happen.”

Beckham last performed with the Spice Girls in 2012 at the closing ceremonies for the London Olympics, and has vowed that it will be the last time as she continues her work in fashion.

As for Christmas gifts this year, David noted that both he and his famous wife asked for very simple gifts this year.

“Socks is always a good one. You know, I'm an Englishman so we – us Brits we love nice socks, so I've asked for socks this year,” he said. “Victoria's list, um, nice pajamas. She loves some nice PJ's, comfy and cozy.”
