Published: June 13, 2025

Hilary Duff celebrated the 10th anniversary of her album 'Breathe In. Breathe Out.' on Thursday, June 12. She shared a heartfelt message on Instagram, reminiscing about the album's lack of major success and jokingly telling fans not to "let it happen again."

Duff, 37, wrote: "It's hard to believe that Breathe In. Breathe Out. is 10 years old today." She shared fond memories of the time, saying it had "some blurry spots and some uncomfortable pain" but she's now grateful for where she is in her life.

Duff also shared a series of photos from 2015, including her "Coolio nails" and Dubsmash videos, which she said were the precursor to TikTok lip syncs. She also spoke about her son Luca's obsession with the Disney Cars movie.

The actress and singer jokingly addressed the album's lack of success, saying: "While Breathe In. Breathe Out didn't have major success, there was still some work on the record that felt authentic. I see you all blaming yourselves on TikTok, not actually your fault (but really it was), just kidding, but don't let it happen again… next time… okay."

Duff also credited the album for introducing her to her husband Matthew Koma, whom she married in 2019. She said: "That's the real reason we have to love her."

The "Sparks" singer concluded her post by asking fans to share their favorite song from the album, saying: "If you were one of the five people who listened to BIBO, drop your favorite song below. Love you."

'Breathe In. Breathe Out.' is Duff's fifth studio album, which was a dance-pop record with electronic influences. The album debuted at No. 5 on the Billboard 200 chart.
