Jessica and Ashlee Simpson's Daughters Twinned in Matching Dresses

Jessica and Ashlee Simpson's daughters have us seeing double.

On Thursday, Ashlee shared photos of her daughter Jagger and niece Maxwell — whom her sister shares with husband Eric Johnson — twinning in matching flower girl dresses at a recent wedding.

"Gorgeous flower girls Maxwell x Jagger wearing @joyfolie," she captioned the photo on her Instagram story.

She also shared a closer look at the cousins in their matching dresses and braided hair. In the photo, nine-year-old Maxwell can be seen with her arms around 6-year-old Jagger. "Cousin love," she captioned the photo.

Ashlee shares Jagger as well as 9-month-old Ziggy Blu with husband Evan Ross. She also shares 12-year-old Bronx Mowgli with ex-husband Pete Wentz. In addition to Maxwell, Jessica and Eric Johnson also have a son, 7-year-old Ace Knute, and a daughter, 2-year-old Birdie Mae.

Last October, Jessica gushed over her sister ahead of Ziggy Blu's birth in a post from what appeared to be Ashlee's baby shower.

"Celebrating new life with my soulmate, best friend, role model, baby sis @ashleesimpsonross," she wrote. "This lady right here is someone we should all aspire to be...determined, hilarious, artistic, loving, soulful, wise, loyal and a champion of motherhood!!! I keep telling her that I looked like this 2 months pregnant 😂 When she needs a good laugh I send her pics of my 3rd pregnancy journey! I love you and I can't wait to be an auntie of 3!"
