Rob Stewart’s son Sean was spotted out in Los Angeles over the weekend, nearly one month after he was admitted to rehab for substance abuse.

The 44-year-old nepo baby was clad in a brown hooded sweatshirt, brown sweatpants, white socks, and white Adidas sneakers.

The troubled musician, who once said being the firstborn son of rock royalty was a ‘curse and a hindrance,’ sported a scruffy shadow of a beard and disheveled dirty blonde locks.

He was spotted shopping in Beverly Hills before zipping off in a white Ferrari with the top down.

In late February Sean voluntarily checked into rehab after his famous family staged an intervention. 

He spent time at the $80,000-a-month Cliffside Malibu rehabilitation facility, where his close friend Scott Disick once sought treatment.

It came months after he split from his wife Jody Weintraub and started dating Charlie Sheen’s ex, Julia Stambler.

‘Sean is in rehab for addiction,’ an insider told DailyMail.com at the time. ‘He’s had a long history of substance abuse, and he decided to get help when he saw that he was falling off the deep end again.

‘There was a family intervention because they were worried. They are all able to see when Sean is sober and when he is not.’

The source added that Rod was proud of his son for acknowledging that he needed help and checking himself in without being forced.

‘In the end, Sean voluntarily checked in to save himself,’ the person shared. ‘Rod is proud of him for getting help. He is expected to do a 90 day stay, which is the norm.’

The pricey facility features views of the Pacific Ocean, plus an outdoor pool and a gym.

Patients receive treatment while enjoying an organic, chef-provided menu, and turndown service in the rooms. Yoga, walks, equine therapy, acupuncture and group counseling are also offered.

Sean has spoken openly about his addiction battle in the past, revealing he was ‘around 13’ and a student at Beverly Hills High School when he first started drinking. He later moved on to harder drugs including ecstasy and heroin.

‘I would go to parties at that age and drink and smoke cannabis and cigarettes,’ he told the Mail in 2012. ‘It was very easy for me to get drugs. I would just walk into a party and someone would hand them to me. I hardly ever paid for them.’

He confessed, ‘First, I got really badly into Ecstasy. Then I started on the prescription pills like Vicodin, and then cocaine. And finally I got into heroin.’

In January Sean and his girlfriend Julia were pictured on a $150 million super yacht with the Stewart clan in celebration of Rod’s 80th birthday.
