The 37-year-old star previously announced her relapse back in April.
Kelly Osbourne celebrated two important milestones this week, and took to Instagram to mark the special occasions.
"Today marks my 37th birthday and I’m five months sober!!! I am filled with so much gratitude it’s almost overwhelming! 💜," the British TV personality captioned a photo of herself holding up a birthday cake along with a screenshot from the 12 Steps app.
Osbourne has been very open about her sobriety journey since revealing she had relapsed back in April.
In May, she spoke with Dax Shepard on his Armchair Expert podcast about relapsing, noting that she made it through the toughest parts of the pandemic and quarantine sober.
"I don't know what happened. Everything started to go f**king amazing," she said at the time. "I'm the girl that when things go incredible and everything's where you think it should be and you suddenly find yourself in what you think happiness is, I went, 'Oh I'm normal now, I'm happy. I don't need any of this f**king s**t. I lasted this whole pandemic without anything.'"
Osbourne had been sober for four years before revealing on her Instagram Stories that she had relapsed.
"This is a little hard for me to talk about, but I've always promised you that I will always be honest with you about where I'm at and what's going on in my road to recovery," Osbourne said at the time. "I relapsed. Not proud of it. But I am back on track."
