Sorry Kim Kardashian -- there's a new "duck lips" master taking the town by storm! Move over, Kimmy K -- because you and your puffy lips have been out puckered by a baby!

We gotta hand it to Rachel Zoe's blue-eyed baby boy, Kaius, for perfecting the quacktastic pout.

The mom of two had a day of family fun on Friday when she and husband Rodger Berman took Kaius and Skyler out to lunch in NYC. And boy, did this family of four look fashionable!

For the big lunch in the Big Apple, Rachel donned a flowing black ensemble, paired with chunky gold jewelry. The stylist to the stars outfitted Skyler in a black tank top, fedora and drop-crotch pants and her nine-month-old donned a navy onesie. Clearly they're the most stylish fam on the block!

Watch out Kardashians -- Kaius is coming for ya!
