Blink-182 drummer Travis Barker did not tolerate the creepy Instagram messages sent by Echosmith drummer Graham Sierota, 20, to his 13-year-old daughter, Alabama Luella Barker.

On Thursday, Barker personally addressed the issue involving his teenaged daughter.

"When I found out a 20-year-old man was trying to get in touch with my 13-year-old daughter by filling her Instagram messages with party invites and compliments, I was disgusted," Travis said in a statement to The Blast. "That’s predatory behavior and there is nothing cool, normal or OK about it at all."

Alabama felt the same way since she shared the now-deleted screenshots of the messages that Graham had sent her on the social networking platform.

“Hey guys! So once again I am bringing this to your attention because I'm a 13 year old girl and he is 21 / 20 super creepy," the “Heartbreaker” singer wrote in the post.

Graham had messaged Alabama “Hi” multiple times, and this questionable behavior started back in 2016 when Barker’s daughter was just 10 years old.

“By the way I’m Graham from echosmith and I think ur beautiful,” one message read.

Alabama did not respond to his messages apart from when he sent an RSVP for a BBQ party at his house to which Alabama exaggerated and said that he’s 40.

Graham, shortly after, responded and told the singer that he just wanted to tell her that he really liked her music. He further apologized for messaging the 13-year-old and pointed out that he’s 20.

“Ok but u understand I’m a child?” Alabama’s last reply read.

"I had invited Alabama to my parents' big family BBQ along with many other people, and it wasn't until she responded that I realized her age at which point I apologized to her,” Sierota said in his apology.

He further stated that he is “really sorry” and that he felt very badly about the issue on hand. He had not realized that Alabama was a minor and assumed that the singer was his age. He explained that he made a “careless mistake” and that this is a big lesson for him.

“I would like to apologize again to Alabama, her dad Travis, and her family,” Sierota added.
