Rumer Willis "proud" to have been sober for six months.
The 'House Bunny' actress - who is the daughter of Demi Moore and Bruce Willis - admits she hadn't "planned" to give up drinking for so long, but she feels really good to be able to say she's in a good place in her life.
She wrote on Instagram: "I will be the first one to say I'm not perfect and I mess up sometimes and every once in a while I get it right but I wanted to share this because I am really proud of myself. Yesterday I celebrated 6 Months of Sobriety.
"It's not something I planned on but after the long journey of getting here I can honestly say I have never been more proud of myself in my entire life. Thank you all for the love and support and remember to be gentle with yourself."
The 28-year-old star's decision comes some time after her younger sister, Tallulah Willis, 23, also gave up alcohol and in 2015 she threw a party to celebrate a year of sobriety.
Tallulah wrote at the time: "Last night was one of the most beautiful nights of my life. I was surrounded in a womb of the purest form of love (sic)"
Rumer previously revealed she isn't worried about getting older because her mother Demi, 54, is still "flawless".
She wrote on Instagram: "That face you make when your mom is flawless and you get stoked to age (sic)"
The former 'Dancing With the Stars' contestant also admitted she carries a lot of "emotional stuff" with her hair.
She said: "I've been dyeing my hair a lot and it's been kind of getting trashed at the ends ... I just got to a point where I just wanted to cut it all off, kind of start fresh.
"I think with women, we put so much of our emotional stuff in our hair, and I think sometimes you just want to kind of chop it off and start over."
