Hard to believe, but there are many famous people who were almost never born. Based on their parents' decisions, these celebrity births almost never happened. Justin Bieber's mom has said that she was contemplating having an abortion when she was pregnant with him. Tim Tebow's mom said the same thing; they even made a commercial about it, which aired during the Super Bowl. Here are also celebrities who attempted suicide and celebs who narrowly missed death.
People make all sorts of decisions that effect the future. If a family decided not to have a child, it is true that the child wouldn't exist to become a celebrity. But, of course, there is no way to know what the future will hold. It only makes sense to make decisions that make sense in the moment. These parents ultimately are probably pretty happy with their decisions, because the kids they decided to have have gone on to fame and fortune. But many other families are happy that they didn't have a child at that moment, because the other choice they could have made would have been devastating for everyone's future.
All we know today is that Justin Bieber and Tim Tebow exist, which probably makes a lot of people happy.
Tim Tebow's parents considered aborting him. Apparently, during his mother's pregnancy she suffered a life-threatening infection, and the drugs she was treated with caused a severe placental abruption. Doctors convinced her to abort the child or risk endangering her own life, but she went against doctors orders and kept the baby.(Source)
