Travis Barker‘s son, Landon, is opening up about his life with Tourette syndrome … which nobody seemed to know about until now.

The 20-year-old influencer shared his health journey Monday — this after a fan on TikTok speculated he may have the disorder. As Landon detailed in the video above … he has a minor case of Tourette’s — which he says he was initially diagnosed with as a child.

Landon recalled first experiencing Tourette’s back in preschool … after a teacher accused him of rolling his eyes at her. Travis’ son — whom he shares with Shanna Moakler — explained the eye-rolling was eventually diagnosed as a tic … a symptom of the neurological condition.

He went on to describe his tics — which also include jerking his head to the side and moving his jaw repeatedly — stuff he’ll do when he says he’s nervous or anxious.

On why he decided to share his diagnosis now … Landon said he just felt like sharing his truth — and fans have since applauded him for his candor.

Landon has been opening up about his personal life quite a bit in recent weeks … having previously confirmed his split from TikToker girlfriend Charli D’Amelio in February.

At the time … Landon told fans that he and Charli split on good terms — as they’re taking time to focus on themselves.

Anyway … interesting little tidbit about Landon here. Never would’ve guessed!
