She's been trying for years and it looks like it's finally paid off. In Touch Weekly is reporting that Jennifer Lopez is pregnant - and she may even be carrying twins!

In Touch claims that Lopez had an ultrasound on September 12 while she was in New York for Fashion Week. An insider said, "The test calculated that she was about 12 weeks pregnant. She's due in the spring."

If you saw the pictures of Jennifer from her justsweet fashion show last week, you probably noticed her baby bump. Despite the fact that she is reportedly only three months pregnant, Lopez's tummy was obviously bulging. This could be because she is expecting twins.

Of Jennifer's visit to the doctor, In Touch's source said, "The way the fetus is lying made it difficult for the doctor to tell if there was more than one baby in there."
