Kelly Osbourne is celebrating two years of sobriety.

The 34-year-old television personality has said she's ''overwhelmed with gratitude'' after reaching the impressive milestone in her sobriety journey, as she took a moment to thank her fans for ''supporting'' her.

In a post on Instagram, she wrote: ''I woke up this morning feeling overwhelmed with gratitude. I can't even put into words how much my life has changed over the last 2 years. To the friends and family that have supported me on this Journey thank you I love you all so much. If you are new to sobriety stick to it life really does get good. (sic)''

The two year milestone comes after 'The Osbournes' star previously admitted she had relapsed in her sobriety battle when life became ''too much''.

Speaking as she marked one year of sobriety last August, she said: ''This past year has been one of the hardest years of my life and I feel it's time share that with you guys. To cut a long story short things got really dark. I gave up on everything in my life but most of all I gave up on myself. Life on life's terms became to much for me to handle. The only way I knew how to function was to self medicate and go from project to project so I never had to focus on what was really going on with me. Something had to give ... and it did. (sic)''

And Kelly recently said she's in a ''great place'' now.

She said: ''I am [in a great place]. I am almost two years sober and it's completely changed my life. I didn't think I could do anything if I wasn't drunk or high, because I was scared of everything. I let it get the better of me. Now seeing that I don't need that and my life is better ... I don't have any drama in my life. I have accepted the fact that - and I know I have said this throughout my whole life but I really understand it now - that I am not perfect and I am never going to be and I don't want to be.''
