Susan Sarandon's actress daughter Eva Amurri Martino has suffered a miscarriage.

The 30 year old took to her blog on Saturday (15Aug15) to detail her heartbreak, revealing she had been nine weeks pregnant with her second child when she lost the baby.

Amurri Martino, who is married to sports analyst Kyle Martino, opened the post by sharing a photo of their one-year-old daughter Marlowe playing on a beach in Hawaii during a family vacation earlier this month (Aug15). In the sand, the beginning of the words "Big Sis" can be seen being washed away by the ocean.

In the post, Amurri Martino describes how she and her husband were "scared and joyful all at the same time" at the prospect of having "two babies under two", and they shared the pregnancy news with family and friends as they celebrated Marlowe's first birthday last weekend (08-09Aug15).

However, days later, tragedy struck.

She writes, "I am sharing in the hopes that we can be a light for people going through similar circumstances, and to remind myself and others that there is no shame in voicing our heartbreaks and allowing others to comfort us. A couple of days ago, the baby I was carrying passed away. I was nine weeks pregnant."

Recalling the moment she learned she had miscarried, she continues, "Just like that, it was all over. I remained in the office and went through the procedure to remove the baby from my uterus... My doctor told me that this was most likely a case of there being an underlying major developmental problem with the fetus, and that it had simply stopped growing. That nature had taken its course in the most brutally honest and simple way that nature sometimes works. He also shared with me that this is heartbreakingly common... Of course the fact that it is common doesn't do anything to help the pain."

She adds, "I have realized in the past 48 hours how incredibly grateful I am for the magic that I have in my life. Of course what I don't have, and what I never will have, is this one little angel who has slipped away from me. And while it will take time for me to make peace with that fact, it gives me a lot of solace knowing that I told - that I have shared its existence with you, that it mattered, and that we loved it. And that will have to do."

Amurri Martino's father is Italian director Franco Amurri. She wed Martino in 2011.
