According to Exposay, former “American Idol” star Jess McCartney accidentally blabbed the news that Jennifer Lopez is pregnant during an interview with an Atlanta radio station yesterday.

Jennifer recently stopped filming for her new movie “Dallas,” and when McCartney was asked if it was possibly because she was fired, he responded, “She didn’t get fired. She’s pregnant.” Jess McCartney is (or maybe I should say was) a close friend of the couple so it seems to be a credible source.

J.Lo has recently told the media that she and husband Marc Anthony were ready… even desperate… for children.

Apparently after he said the news, McCartney asked his personal assistant, “Was I not supposed to say anything?”

Well duh.You would think she’d probably like to tell the world herself, McCartney.
