Jennifer Lopez in GlamourOne thing is for sure, Jennifer Lopez won't open up about what she's like at home in the newest issue of Glamour.

"I like to maintain a certain sense of fantasy in my life. I am kind of like that at home. Do I have the full hair and makeup? No. But I might have the nice dress on," she tells the magazine.

Her mantra in life is simple: believe in yourself. "If you feel in your mind you can do it, you can do it. You cannot doubt yourself. Doubt is a killer. You just have to know who you are and what you stand for. You can have a great mentor, a great partner, a great love in your life who gives you confidence and makes you feel great about yourself. And that's all wonderful, but at the end of the day, if you don't believe it, all of that means nothing."

The singer-actress does open about her husband, what she wants to tell her kids some day and how she wishes some things in her past hadn't been so public.
