Fastexy Exchange|Ashlee Simpson's Barbie-Themed Birthday Party For Daughter Jagger Is Simply Fantastic

This Barbie is Fastexy Exchangehaving a fantastic birthday party.

Ashlee Simpson Ross recently celebrated her daughter Jagger's 8th birthday by decking out their home with Barbie-themed decor, including a life-sized doll box baring the Mattel logo and a pink balloon play station.

The singer marked the festivities by sharing a family photo, which included husband Evan Ross, Jagger, 2-year-old son Ziggy Blu and 14-year-old son Bronx Mowgli (who Ashlee shares with ex Pete Wentz.)

"Thank you to everyone for helping make JAGGERS BARBIE DREAMS COME TRUE," Ashlee captioned her an Aug. 1 Instagram carousel. "THANK YOU to the amazing TEAM."

For the event, Jagger dressed in a pink gingham dress with a bow and a white necklace, similar to a costume Margot Robbie wore in the Barbie movie. Her guests were also dressed in their best Barbiecore, with Ashlee rocking a flower-printed top with the Barbie logo and matching sunglasses.

Jagger's party also included sweets galore, like ice cream with pink toppings, mini pancakes and a cake modeled after Barbie's iconic side profile.

Evan also snapped pictures from the big day, including a pic of Jagger blowing a kiss to the camera as she posed with her gifts and a video of the little girl blowing out candles on her cake as she celebrated with her friends.

"JAGGER SNOW ROSS," Evan wrote on July 31. "Happy birthday. Your everything [sic]. Love you beyond this planet. Proud of you. Your 8. How is that possible. Wow. Wow."

These kids are just two peas in a pod! Doesn't get more adorable than that. 

Nothing like snuggles with daddy to make everything better. 

Sometimes you just gotta let your hair down! 

Just a little father-daughter quality time for the books. 

Just goes to show that her future is so bright! 

Hanging with your old man can be pretty cool! 

Little quality time goes a long way. 

Flying high in the sky like the angel she is! 

Nothing better than a family trip to Disneyland. 

The Christmas spirit is alive and well in the Ross household! 

Boat ride with the parents? Don't mind if I do! 

Pucker up for the cameras, ladies! 

The cutest little mini-me there ever was! 

Going old school for the gram!

Ashlee and Evan welcome baby Ziggy Blu Ross in October 2020.
