J. Lo Makes It Official!

Jennifer Lopez announced her pregnancy on Wednesday. Finally!

The singer/actress broke the news to the crowd in Miami on the very last stop of her U.S. tour, PerezHilton.com has learned.

The audience at the American Airlines Arena erupted with screams and applause, we’re told. “J. Lo got very emotional.”

Though it had been reported for weeks, Lopez had nor confirmed her pregnancy until Wednesday.

”Marc and I are expecting,” she told the crowd.

Her husband and touring partner, Marc Anthony, then bent over and started kissing La Lopez’s belly.

”I didn’t know she was going to talk,” Anthony said.

Jenny didn’t say whether it was a boy or a girl or twins, as we were the first to report.

Felicidades!
