On The Right Track! Kelly Osbourne Is 'Filled With Gratitude' As She Celebrates 5 Months Of Sobriety

Kelly Osbourne had two good reasons to celebrate on October 27: not only was it the star's 37th birthday, but that same day marked her fifth month of sobriety!

The Fashion Police alum announced the good news on Instagram, where she showed off a cake and a screenshot from her 12 Steps program, which noted she's been without alcohol for 154 days.

"Today marks my 37th birthday and I’m 5 months sober!!!" she captioned the shot. "I am filled with so much gratitude it’s almost overwhelming! 💜."

Prior to the milestone, the reality star had been sober for four years straight, but she experienced a relapse in early 2021 amid the stress of the pandemic.

"I don’t know why my nervous breakdown happened at the end of the lockdown. I made it all the way through, everything was great and my life was perfect," she recalled to Extra in April. "I’m that girl that when everything is going great I need to f**k it up a little and make everything a little bit worse in my life."

"I am an addict and had thought that I had enough time under my belt and I could drink like a normal person, and it turns out I cannot and I will never be normal," the Project Runway Junior judge continued. "I don’t know why I even tried it. It’s not for me, and it took me a matter of days and I was like, 'Done, not doing this.'"

At the time, she was doing "great" in all aspects of life, which triggered her to believe, "I’m not an addict anymore." But drinking, "on top of that pandemic fever ... it all just got too much," she said.

Osbourne acknowledged that sobriety is something she'll have to deal with for the rest of her life, admitting, "it’s never going to be easy."

Though she could keep her struggles to herself, she believes that being open about the situation will benefit her peers.

"Through being accountable and owning your own journey and sharing what you can go through you can help other people," she explained. "That’s why I came clean. I could have sat here and nobody would know."
