4. Minnie Driver

Although Minnie Driver didn’t reveal her baby daddy for the first few years of her son Henry’s life, people found out who he was years later.  In 2012, she dropped the news that the dad was a writer on “The Riches,” Timothy J. Lea. She commented that she didn’t feel the need to protect him anymore, expanding, “We weren’t together, and he wasn’t directly in the business, so I chose to protect him and not have a rain of publicity.”

5. Geri Halliwell

This Spice Girl had a daughter named Bluebell in 2006, and purposefully kept the father’s identity a secret. When asked if she was with anyone, she gave the blunt response: “ “No, and to be honest, I don’t really care.” People speculated and gossiped, but it was ultimately revealed that Sacha Gervasi, a screenwriter with whom she had an affair, was the father. On being a single mom, Halliwell said, “Obviously, we have our ideals which are much more traditional, of having both parents, but we can’t all have that.”
