Ashlee Simpson Throws Elaborate "Barbie" Party For Daughter Jagger's 8th Birthday

Simpson welcomed her second child — her first with Ross — on July 30, 2015. Simpson announced her daughter Jagger's birth on Instagram with a photo that read, "We are overjoyed about the birth of our precious baby girl Jagger Snow Ross."

As evidenced by all the photos Simpson and Ross share of Jagger, it appears the little one loves styling clothes and has quite the vibrant personality. And from throwback photos Ross has shared of himself as a kid, it's clear Jagger is his little mini me.
