Christina Perri has suffered a miscarriage

Taking to her Instagram account, the 33-year-old singer-songwriter wrote: "Today i had a miscarriage. Baby was 11 weeks old at the time. We are shocked & completely heartbroken. We were only 1 week away from sharing the news so i feel like it's also important to share this news too. I want to continue to help change the story & stigma around miscarriage, secrecy and shame.

"I am so sad but not ashamed. I am ever reminded how amazing and powerful women are at making life and at healing. To all the mothers who have been here and who will be here, i see you and i love you. I am so sad but not discouraged. When the time feels right we will try again, but today, we mourn our little life lost. (sic)"

Christina and her husband Paul Costabile - who got married in 2017 - already have daughter Carmella, who will be two next week, together.

The 'Jar of Hearts' hitmaker previously opened about her battle with post-partum depression, which hit her "the hardest" when she stopped breastfeeding her little girl.

She explained: "That got me the hardest when I stopped breastfeeding around Christmas. I was so sad and so dark. We're almost made to pretend it's not happening, like, 'It's fine. I've got this.' "

However, Christina was able to work through her battle with mental health with the help of more than 15,000 mothers who reached out to her to share their similar stories.

She said: "What really helped was talking about it. It was just overwhelming. It made me feel so much better. All the women said 'me too, me too, me too' and really got me through it. I've got my mommy tribe that got bigger because of that."
