Christina Still Quiet About Baby Bump

Despite the predictions of many Hollywood insiders that Christina Aguilera would choose her performance of "Steppin' Out [with My Baby]" at Sunday's Emmy awards to finally break her silence of the topic of her now-quite-obvious pregnancy, the soulful songstress instead gave no hint of a big reveal during her duet with music legend Tony Bennett.

This latest bit of standing mute about her bulging belly comes hot on the heels of Paris Hilton revealing it to everyone in attendance at a pre-VMA party last weekend and, two days later, Emmy producer Ken Ehrlich letting it slip to an OK! reporter during a tour of the new Emmy stage.
