Rob Lowe gifts son John Owen 5-year sobriety chip: ‘I’m proud of you’

He’s been there through the highs and the Lowe’s.

Actor Rob Lowe was overjoyed to gift his son, John Owen Lowe, a chip to mark five years of sobriety during their appearance on “The Drew Barrymore Show” Thursday.

Barrymore discussed her own sobriety with the duo, saying her daughters Olive, 10, and Frankie, 8, understand that she cannot drink alcohol.

“They support me through my pitfalls,” she said of her daughters. “And you guys are an incredible family unit that supports each other through every high and low, everything.”

The heartfelt confession prompted Rob to open up about his own sobriety journey, revealing he’s now gone 33 years without alcohol.

“We do, and to be able to share recovery — you’re in recovery, I’m in recovery — I’ve got 33 years in recovery … Johnny’s got five years,” the actor said.

The 59-year-old then pulled out a sobriety chip out of his pocket, which he gave to his son.

“In fact, Johnny’s five-year birthday was on Saturday, and Johnny I want to give you your five-year chip,” the “Parks & Recreation” star said.

“I love you. I’m proud of you,” he said to John Owen, 28.

“I’m speechless. I usually have a witty retort. I don’t have one for that. That was very nice of you,” he said to his dad.

Rob, for his part, has been very open about his own path to sobriety, and previously credited Aerosmith frontman Steven Tyler for helping him kickstart the booze-free journey.

Tyler, 75, offered a few words of encouragement — even though they had never met in person.

“I was probably sober two or three weeks, maybe, and I got a phone call from Steven Tyler, who I did not know,” Rob revealed in 2014. “He called me and said, ‘I heard you’re in recovery and I just wanted to say, ‘Hey, you’re going to do great.’”

Rob said the rocker’s call helped changed his perspective and he thought, “If it’s good enough for Steven Tyler, it’s good enough for me.”

“He’s a big part of who I am today,” he added.

In 2014, the actor shared that he got sober in order to stop cheating on his wife, Sheryl Berkoff.

“I had met my now wife, Sheryl, and was attempting my first try at monogamy, which was not really in my nature at the time, and I wasn’t able to do it,” the “West Wing” star told Haute Living. “It made me examine how I was living.”
