Although many stars have turned to in vitro fertilization to conceive, Jennifer Lopez never considered it an option -- and says she never will.

"When it comes to family and relationships, I’m quite traditional," the star, 40, tells the February issue of Elle magazine. "Just because of the way I was raised. And I also believe in God and I have a lot of faith in that, so I just felt like you don't mess with things like that."

Lopez -- who is mother to 22-month-old twins Max and Emme with hubby Marc Anthony -- portrays a woman who decides to have a baby through artificial insemination in the upcoming romantic comedy, The Back-Up Plan. Still, she doesn't believe the process is for her.

"I guess deep down, I really felt like either this is not going to happen for me or it is," she tells Elle. "You know what I mean? And if it is, it will. And if it's not, it’s not going to."

Being a mother, however, isn't stopping her from working to remain a pop icon.

"This is what I do -- what, because I have kids and a husband now I’m not supposed to be me?" she says. "I'm a more heightened me if anything. Hyper J.Lo. Everything I wanted before, I want twice as much now... Being an artist doesn't start because you're 21, and it doesn't end because you're 51. You are who you are until the day you die."
