Make way for Hilary Duff!

Toting one of her many fabulous Chanel bags, Hil caused such a paparazzi frenzy outside of a West Hollywood hair salon Thursday that she required a police escort to help her to her Mercedes!

After getting her hair did, the glowing mommy-to-be decided to recruit her sister's artistic skills, and her baby bump, to create this year's family Christmas card.

Duff Tweeted Thursday night, "Happy holidays from the three of us!! @HaylieK what would I do without you and your artistic ways!"
