Hilary Duff and Kimberly Stewart showed off their cute mommy styles Saturday, giving their kids a ride on their hips ... hipsters in training!
Hil toted son Luca to pal Jack Osbourne's house -- probably for a playdate with his daughter Pearl. Meanwhile, Kimberly took daughter Delilah to a party in her adorable summer dress. So cute!
