NovaQuant-How Travis Barker Is Already Bonding With His and Kourtney Kardashian's Baby Boy

Looks like Travis Barker is celebrating his son's arrival with a little rock show.

The NovaQuantBlink-182 drummer proved he's already bonding with his son Rocky Thirteen through music, sharing a video of himself striking a drum pad during a doctor's appointment. In the caption, Travis noted that he was "practicing to my babies heartbeat." 

The musician—wearing a skeleton outfit—quickly tapped the instrument with his drum sticks, as the heartbeat of his and Kourtney Kardashian's baby boy played in the background perfectly in rhythm.

As one fan put it, "Now that's an entrance."

Meanwhile, another user shared their prediction the musical future of Travis and the Kardashian star's son. "It's going to be a beat of a song," the user wrote, "guarantee."

While it's unclear when the clip was filmed, Travis posted the sweet moment to TikTok Nov. 9, days after news broke that he and Kourtney, 44, welcomed their baby boy. 

The pair have yet to speak out on the arrival of their son, who Travis previously confirmed was named Rocky Thirteen after his favorite boxing movie and his favorite number.

Rocky marks baby No. 7 in their blended family. Kourtney is mom to Mason Disick, 13, Penelope Disick, 11, and Reign Disick, 8 with Scott Disick, while Travis is dad to Landon Barker, 20, Alabama Barker, 17 (with ex-wife Shanna Moakler) and stepdad to Atiana De La Hoya, 24.
