Chrissy Teigen reached a milestone.

The star is no stranger to sharing her thoughts and struggles online and in one of her most recent Instagram posts, she revealed that she’s sober.

Teigen, 35, shared a short video clip of herself gleefully dancing and singing to the song “Good Morning” from “Singin’ in the Rain” — though she stumbled over some of the lyrics.

For the joyful moment, she wore a pink and blue one-piece swimsuit in a room lightly decorated for the Christmas holiday.

The singer has previously spoken about her relationship with alcohol. In a 2017 interview with Cosmopolitan, she said that she was taking a break from booze because she felt she was “point blank, just drinking too much.”

“I got used to being in hair and makeup and having a glass of wine. Then that glass of wine would carry over into me having one before the awards show. And then a bunch at the awards show,” Teigen explained. “And then I felt bad for making kind of an a– of myself to people that I really respected. And that feeling, there’s just nothing like that. You feel horrible. It’s not a good look for me, for John, for anybody.”

The mom to daughter Luna, 4, and son Miles, 2, also found that alcohol was a hindrance to her recovery from post-partum depression.

“Nobody really brought it up to me,” she said at the time of her drinking habits. “They just assumed that it was OK because I always felt OK the next morning. I knew in my heart it wasn’t right. It makes you very short with people. People think it’s cutesy and fun to go on these boozy brunches, but there’s more to it. I’ve never once been like, ‘I’m sure glad I had that boozy brunch!'”
