Travis Barker is proud of his son Landon to join him on Blink-182 tour

“I've been helping him with music, while I'm home, here and there,” said Travis Baker about his son.

Travis Barker plans to make his upcoming tour a family affair.

Speaking exclusively with PEOPLE at his first "run and wellness experience," Run Travis Run, on Saturday, July 6, the Blink-182 drummer, 48, expressed pride in having his 20-year-old son, Landon Barker, join him and the band as a guest artist for some tour dates. He mentioned Landon had been rehearsing at home and that he's been mentoring him in music.

“I've been helping him with music, while I'm home, here and there,” he added of Landon. “So yeah, I'm really proud of him.”

At the Los Angeles event, which included a 5K run and other wellness activities, Barker had the support of his family, including wife Kourtney Kardashian and stepdaughter Atiana De La Hoya.

Travis and Kardashian, 45, have an 8-month-old son, Rocky Thirteen Barker, and each have three children from previous relationships. Kardashian has Mason, Penelope, and Reign with ex Scott Disick, while Barker shares Landon, Atiana, and daughter Alabama with ex-wife Shanna Moakler.

Both Atiana, 25, and Kardashian were seen at the Run Travis Run event dressed in all-black athletic wear, mirroring Travis's attire.

Throughout the pre-concert wellness event, which Travis initiated to encourage outdoor activity, Kardashian stood by her husband's side. The couple also showed affection, sharing a kiss among the event participants.
