Eric Christian Olsen and Sarah Wright Olsen have become parents for the fourth time

The couple wrote in a joint Instagram post: "She's here!! Ocean Rain Olsen. Born 6/17 12:37am - 11 pounds 4 ounces.

"Grateful beyond words for our amazing team that helped us get her here safely during an incredibly complex birth. Cannot wait to share all the details of this day."

The post featured a series of posts of the couple in the hospital and posing proudly with their new baby.

The couple - who married in 2012 - announced in February they were expecting their fourth child, with the happy news coming just a few weeks after their home in Malibu was destroyed by the Los Angeles wildfires.

In an emotional post, the Spinning Out actress admitted it was "so hard" to say goodbye to their house because of the memories the family had of the abode.

She wrote on Instagram at the time: "It's impossible to put into words these last few days. We are together and safe and surrounded by love. Thank you to uncle Dave and aunt Dani who took in so many of us. We lost our home. It was one of the first areas to go.

"Our kids have said 'We all took our first steps there.' It's so hard to say goodbye to our gorgeous town, our special school and this place we have loved for 13 years. But we are so so grateful we are together and for the outpouring of love.

"We have received so many messages from friends offering their homes, food, clothing, hugs, things for the kids, support and we are just blown away. It's what keeps making us tear up. Thank you it means so much to us."
