Superstar Jennifer Lopez has revealed that she used to worry that her success might be short-lived. 

Speaking to Wendy Williams this week, the 'On The Floor' sensation admitted that she always felt as though she was waiting for her luck to run out: "When you first start in this business, you think, 'This is going to run out' or 'It's going to finish at a certain time' or 'If I reach a certain age I won't be relevant'."

She confessed that luckily, it's something she no longer struggles with because she feels more confident and motivated as she gets older: "I just get better and better with more experience and more life. I have more to give to what I do and that's what I look forward to when creating this record."
