Jennifer Lopez did not make her expected baby announcement this weekend in Madison Square Garden, but she had a tell-tale smile on her face and a visible baby bump that left fans scratching their heads.

Wearing a loose-fitting Roberto Cavalli top, J. Lo paused for a moment as the crowd cheered and geared up for the big news.

Instead, she smiled and asked, "What?" as she looked around the stage.

There are reports that she's expecting twins, but Jennifer's lips are sealed.
