"It can't help but bring the families' focus on whether she will be a mother herself one day."Millions of fans were crushed when Rachel and Gosling broke up in 2008.
She later dated Michael Sheen and Patrick Sambrook, a Canadian music manager.
Her brother and sister-in-law announced that the baby is due on September 2 via their baby gift registry website, saying: "Hi Everyone!Thank you so much for helping bring our baby boy into this world surrounded by love and happiness.We really appreciate everything and all the help during this amazing time!!Dan and I are so happy and excited to share this with you."Relatives were overjoyed at the baby news.
"There's always a sense that the oldest child should be the first to have a baby of course, but there's still time for Rachel.She's at that stage in her life where friends, family and exes such as Ryan are all popping out babies." So her single childless status was duly noted.
