Hilary Duff Reveals She's Expecting A Baby Boy

Boy or girl, we've had our eyes glued to Hilary Duff's growing baby bump. But now that we know the sex of Duff's forthcoming bundle of joy we can start speculating baby names. Gordo, anyone?

Duff took to Ellen Degeneres to reveal that she's expecting a baby boy, explaining that before she found out for sure, she "had a feeling it was a boy." Duff, who is a little over four months along, is already showing quite a bump and looks positively glowing with her growing baby accessory.

This will be the first child for Duff and husband, Mike Comrie.
