Rob Lowe presented his son John Owen with an extraordinary surprise as he marked five years of being dry. The father and son duo were featured on The Drew Barrymore Show to discuss their brand new Netflix comedy series Unstable on Thursday.

While there, Barrymore, 48, praised the couple for their unwavering support of each other. She confided about her own recovery process, and remarked that her daughters, Olive, 10, and Frankie, 8, understand why she abstains from alcohol - because "it's just not for me."

Lowe, who has been sober for 33 years, revealed that his son had recently celebrated his fifth year of sobriety. To commemorate the occasion, the actor presented Owen with a sobriety chip during their interview on the show.

Expressing his pride and affection, he said to his 28-year-old son, "I love you."

Expressing his surprise, Owen admitted that he was unable to think of anything to say; a phenomenon that is not commonly encountered.

Last month, Owen delved into his sobriety journey and highlighted the important role his parents played in aiding him in overcoming his addiction when conversing with PEOPLE at the Los Angeles premiere of the Netflix show.

He went on to say, "It's really humbling to have had the support of my parents when I needed it the most. It's heartbreaking to think that some folks don't have that, so I'm incredibly lucky that I did and I'll never forget it."

Lowe also shared his insights on addiction and how he had learned over the years that someone has to be ready to make a change. He emphasized the importance of being there for his children and supporting them until they are ready to take the path towards recovery.

The emotional moment between Lowe and Owen on The Drew Barrymore Show serves as a reminder of the importance of family support in overcoming addiction. It also highlights the power of sobriety chips as a symbol of progress and a testament to one's commitment to staying sober.
