Her heartfelt note was accompanied by a video that compares her life in the middle of her struggle with addition to how it has changed since she’s gotten sober.

As the video begins, Paris is smoking and drinking excessively on camera during social events, parties and privately. As the video progresses, the “Let Down” singer is seen crying, before things take a turn and she is shown smiling more, and not doing drugs or drinking. She even shares cute moments with her fiancé Justin Long.

When the video ends, a final message of gratitude flashes across the screen.

“For those that helped me on this journey, if only just the beginning, middle, or the whole time so far, you know who you are and I owe you my life, thank you,” she wrote. “5 years, Thank God.”

Just weeks before Paris celebrated her latest sobriety milestone she marked another major life event: her engagement to producer and bandmate Justin. And she announced the news with a sweet birthday tribute dedicated to her love.

“Happy birthday my sweet blue,” she began her Dec. 6 Instagram post. “Doing life with you these last years has been an indescribable whirlwind and i couldn’t dream of anyone more perfect for me to do it all with.”

She continued, “Thank you for letting me be yours. I love you.”
