The actress and singer Natalie Imbruglia is a young mother. The 44-year-old Torn hitmaker shared her happy Instagram news with fans and posted a sweet photo of her holding her little son's hand. "Welcome to the world … Max Valentine Imbruglia," she labeled the sweet shot. "My heart bursts." The celebrity friends of the Australian star quickly congratulated the first-time mother and singer Sophie Ellis-Bextor wrote, "Yay! Hi Max! Congratulations, Mom! "Imbruglia announced in July that she was pregnant following in vitro fertilization (IVF) with the help of a sperm donor." For those of you who know me, this is something that I have been wishing for a long time. " "I am blessed that this is possible." Natalie, who was married to former Silverchair frontman Daniel Johns until they separated in 2008, still has to reveal the identity of her child's father.
