John Stamos is heartbroken after the death of his lifelong friend, Mike Owen, a bond stretching back to their childhood. The beloved 'Full House' star shared the devastating news on social media, leaving fans and followers deeply saddened.

In a touching post, Stamos recounted how he learned of Mike's passing while aboard a flight to Detroit, receiving the news through a text from Mike's brother. Mike, according to Stamos, suffered a sudden heart attack, though further details surrounding the incident remain unclear.

Stamos described Mike as his 'everything friend,' reflecting on their nearly lifelong friendship that began when they were just 11 years old. He penned an emotional tribute that included fond memories, emphasizing how they enjoyed adventures at Disneyland and shared countless moments together. He wrote, 'From the moment we met, we were inseparable, two boys finding magic in Disneyland and in each other’s company. Mike had this way of making the world feel steady.'

He painted a vivid picture of Mike as a true friend who embraced being in the background and supporting Stamos throughout his career. 'His gift was something most people spend their lives chasing: contentment,' he shared, highlighting Mike's humble nature and ability to find joy in simplicity.

The pair had shared their last adventure together just three weeks prior at Disney World, reliving their childhood joy and innocence. Stamos reflected on this bittersweet experience, stating, 'Losing Mike feels like losing a piece of myself, like chapters of my story are missing now.'

In his heartfelt message, Stamos encouraged everyone to appreciate the loved ones in their lives and to express their feelings while they can.

This loss comes on the heels of another somber piece of news for Stamos and his 'Full House' family, as his co-star Dave Coulier recently revealed he is battling stage 3 non-Hodgkin lymphoma. Stamos pledged to stand by Coulier's side during his fight, reaffirming their deep connection as brothers.

Adding to the emotional weight, the duo also mourned the loss of their friend and mentor, Bob Saget, who tragically passed away in January 2022 due to an accidental head injury. Stamos calls on his fans to cherish every moment, reminding everyone of the fragile nature of life and friendship.
