A source also reveals that the couple are overjoyed by the news.
"It's a dream come true. She and Marc are over the moon," Us quoted the source, as saying.
Further rumours that JLo was pregnant were fuelled after she made an appearance on MTV's Total Request Live on October 8 to promote her new CD, Brave.
Co-host Damien Fahey said at the time: "I've been around a lot of pregnant women. She walked around like a pregnant woman, sat like a pregnant woman and stood like a pregnant woman."
