Hilary Duff's Undercover Bump

Sporting a layered look, mom-to-be Hilary Duff kept her bump under wraps as she was spotted out and about in Toluca Lake, California today (February 1).

With her due date fast approaching, the 24-year-old actress, who is married to NHL star Mike Comrie, has entered the home stretch of her pregnancy - and it sounds like she's feeling it!

"Just when I think this baby bump couldn't possibly get bigger.... Boom... it does! #gettinguncomfortable," Hilary Tweeted this week.

That admission came just a few days after she took to Twitter with complaints of pregnancy-related insomnia: "ugh... can't sleep... #officiallybabyspersonaltrampoline!"

All things considered, though, the lovely mom-to-be hasn't had it too tough. A few months ago she gushed of pregnancy, "I think it's such a miracle. I feel so lucky that I've had an easy pregnancy and hope it stays that way."
