While McCaffrey was jamming out, he was joined by his brother-in-law, Gus Culpo, the brother of his supermodel wife, Olivia Culpo.

The video opened with Gus playing the piano and then transitioned into McCaffrey taking the lead.

“Ear Training with Uncle Gus @gusculpo,” McCaffrey wrote in the video’s caption.

Three years ago, McCaffrey’s musical talents went viral when he was seen playing a piano solo at a Zach Bryan concert at Red Rocks Amphitheatre near Morrison, Colo.

Since then, McCaffrey has regularly made cameo appearances playing piano with Bryan’s band.

Two days ago, Roman got to see his dad on the football field for the first time.

Before the 49ers’ dominant 38-17 victory against the Raiders on Sunday, Olivia Culpo was spotted greeting McCaffrey on the San Francisco sideline during pregame, where they were joined by Roman and their daughter, Colette.

McCaffrey had one rushing touchdown and one receiving touchdown. He also ran the ball 18 times for 68 yards.

While Roman has seen (and heard) his dad’s talents on and off the football field, it comes while the 49ers have the NFC’s best record at 7-1 and have legitimate aspirations of winning the Super Bowl.

McCaffrey and the 49ers will return to the football field on Sunday, when they play on the road against the Cowboys.
