I guess you've heard this by now: Jennifer Lopez is pregnant. In Touch Weekly broke the news:

"She's about twelve weeks pregnant," an insider tells In Touch. "She's due in the spring."

They claim J Lo's pregnancy is a result of in-vitro fertilization ( I didn't know Jennifer Lopez had problems conceiving) and quote an anonymous friend:

"becoming a mother is Jennifer's dream," a friend says. "She's over the moon."

In Touch Weekly doesn't explain who's friend is this. They also say J Lo may be pregnant with twins, and call it a successful fertilization!? Anyway, this can be just another "Jennifer Lopez is pregnant" rumor, according to Daily News:

In Touch Weekly proclaimed yesterday that Jennifer Lopez is finally expecting a baby, or maybe even twins - but that's news to hubby marc anthony. "Everyone calls about this every month with the hopes that they'll hit the mark," Anthony's rep told us, "but no. No." A flack for In Touch said it's sticking by the story.

I must say Jennifer actually has a suspicious bump in her belly, as you can see in the photos:
