Has remained tight lipped on her pregnancy and leaving her growing bump to do all the talking, Jennifer Lopez at last long broke her silent and has finally made it official that she and husband Marc Anthony are expecting a baby.

Just a week after fellow expectant celebs Christina Aguilera and Cate Blanchett spilled the beans on their pregnancy, the Bronx singer unexpectedly broke the obvious news during a gig at Miami's American Airlines Arena Wednesday night November 7th which was the last show of her and hubby's El Cantante Tour.

"We didn't want to say anything before because we didn't want to take away from the tour, but Marc and I are expecting," so Lopez told the crowd of concert-goers. Hubby Anthony interrupted "I did not expect her to say anything" before then shrugged his shoulders, caressed his wife's stomach, then leaned over and kissed her belly.

The songbird went on saying, "I felt that now that we're ready and we're going to go away and have a little bit of time alone it was the right time," and turning to Anthony adding, "I hope you don't mind."
