The Blink-182 drummer paid a touching homage to his baby on Instagram, posting some black and white images.
The musician captioned the photo, “So proud of you @landonasherbarker.”
“It has been a real pleasure and honour to raise you,” he continued, “and I can’t wait to see all the fantastic things you’ll do and become.”
“Congratulations on graduating, I love you,” Barker said at the end of his post.

In the comment section, Barker’s new wife and Landon’s stepmom, Kourtney Kardashian, wrote, “I am so proud of you @landonasherbarker!!”
“I Love you!” Landon replied in response to the message.
Landon and Alabama, Barker’s son and daughter with ex-wife Shanna Moakler, are his children. From 2004 through 2008, the two were married for four years.
From his former marriage to Oscar De La Hoya, he has a strong kinship with Moakler’s daughter Atiana De La Hoya.
Kardashian and her ex-Scott Disick’s three children, Mason, Penelope, and Reign, now have a stepfather in the 46-year-old.
