Lopez did not announce pregnancy at show

Jennifer Lopez did not announce that she is pregnant at a show in New York on Saturday, despite speculation that she intended to do so.

According to reports last week, the 'Do It Well' singer planned to confirm rumours that she is expecting her first child by husband Marc Anthony.

But Lopez failed to reveal the news during her performance at Madison Square Gardens and it is now rumoured that she will speak out on the Late Show With David Letterman.

The talk show's producers are attempting to persuade her to make the announcement on Tuesday night's programme, claims gossip website Perezhilton.com.

Lopez has repeatedly denied reports that she is due to give birth next spring.
