Despite an internet buzz that Jennifer Lopez was in labor on Monday, Marc Anthony's reps say the rumors are "not true."

"It's not true," the rep tells Us Weekly. "We have been getting the same phone calls since last week. Everybody figures it is happening around now so they have started throwing out the story hoping they will be right and be the one to break the news but it isn't yet."

Jennifer's rep has refused to comment on the due date in the past. Both Lopez and Anthony have tried to keep the pregnancy hush-hush from announcement to delivery.

Lopez is likely to give birth soon though. Rumor also has it that J.Lo is having twins!
