Transformers star Megan Fox and husband Brian Austin Green have welcomed their third child together. The Hollywood couple shocked fans with news of their pregnancy in April, as she had split from Green in 2015.

According to E! News, the 30-year-old actress gave birth to a baby boy named Journey River Green. The couple are also parents to Noah and Bodhi.

The two tied the knot in a private ceremony in Hawaii in June, 2010 after several years of dating. They originally got engaged in 2006, but called it off in 2009, only to reunite in 2010 and walk down the aisle. Green already has a 14-year-old son Kassius with ex-girlfriend Vanessa Marcil.

In June, Megan's father, Franklin Thomas Fox had revealed they are expecting another boy. He said: "Megan is an amazing mom and I can't believe she is going to have three boys. Becoming a grandfather has been a wonderful experience and brought us all even closer together."

"All I can say is they are together and they are happy. I've met Brian a tonne of times now and he is a great guy ... I am the grandfather of her two gorgeous boys and now she has another boy on the way. I couldn't be prouder of the woman my little girl has become," he added.

Megan has previously voiced her desire to have more children. She told U.S. talk show host Chelsea Handler: "I knew I was always going to be a mother, I felt like that was always a big part of my path, but I never knew I was going to have three in such rapid succession."
