Travis Barker Adorably Twins With His & Kourtney Kardashian's Son Rocky

Rocky Thirteen Barker is following in his dad's footsteps.

On Monday (November 3), Travis Barker shared an adorable photo to his Instagram Stories of his matching "tattoos" with his youngest son, whom he shares with wife Kourtney Kardashian, per People. In the snap, Rocky has what appears to be an airbrushed temporary tattoo of a skull on his leg, twinning with his dad who sat next to him show off his own real skull tattoo. The toddler, who turned 2 years old on Saturday, November 1, also had a tattoo of a guitar surrounded by stars on along his arm.

"Like father like son 💀" the blink-182 drummer wrote over the pic.

Barker celebrated his son's birthday over the weekend with a sweet Instagram shoutout to the little one, sharing a photo of Rocky in a jersey emblazoned with the number 13 as he praised his youngest child.

"Happy Birthday my Rocky 13," he wrote. "You're such a special soul, and you make every day brighter. I love you. No one's cooler. Guitars, drums, pirates, boom boom pow and Angus Young forever."

In addition to Rocky, Barker is a dad to son Landon, 22, daughter Alabama, 19, and stepdaughter Atiana De La Hoya, 26, with ex-wife Shanna Moakler. Kardashian also shares three kids — son Mason, 15, daughter Penelope, 13, and son Reign, 10 — with ex Scott Disick.
