It looks like Jenny from the block will soon be playing with baby blocks. In Touch can exclusively reveal that Jennifer Lopez is going to be a mother. "She's about twelve weeks pregnant," an insider tells In Touch. "She's due in the spring." After years of trying to start a family with husband Marc Anthony, she was finally successful with in vitro fertilization — so successful, in fact, that there's a possibility she's having twins! Whether she has one baby or two, "becoming a mother is Jennifer's dream," a friend says. "She's over the moon."
