Parenting is a job you learn while doing. So says Jennifer Hudson, who still doesn’t feel she has the “right answers” to parenthood.  The singer-and-actress — who has nine-month-old son David with fiancé David Otunga  admits balancing parenthood with her career is still a learning curve but she feels she is doing well so far.  She said: “It’s still very new to me. I don’t feel like I have the formula or the right answers just yet. But so far, so good.”
