"Maxwell has her momma's pout down pat," the Fashion Star mentor tweeted earlier today with a picture of the duo out and about on Saturday.
The snapshot showed a pregnant Simpson (who accidentally spilled that she's expecting a little boy) looking chic in a navy blouse, jeans and shades, while Maxwell made direct eye contact with her baby blues and, of course, showed off those full baby lips.
The pair met up with 28-year-old Ashlee Simpson and her 4-year-old son, Bronx, that same day for some quality family time and a little Toys "R" Us shopping spree.
Meanwhile, Jess has been continuing to work on the new series Fashion Star, and even gave fans a sneak peek at some behind-the-scenes footage from Friday's show. Maxwell was also present and stole everyone's attention as expected.
Just look at that pout!
