Ashlee Simpson Ross Takes Daughter Jagger, 9, to See Olivia Rodrigo in Concert: 'What a Fun Time'

Ashlee Simpson Ross had the ultimate girls' night out with her daughter!

On Friday, Aug. 16, the "Lala" singer, 39, posted photos and videos on Instagram of her daughter, Jagger Snow, and some friends attending Olivia Rodrigo's GUTS world tour at the Kia Forum in Inglewood, California.

"Nothing cuter than taking the girls to see @oliviarodrigo what a fun time ❤️," Ashlee captioned the carousel, which featured a photo of Jagger, 9, posing with her friends, a snapshot of the group posing with the "drivers license" singer and a video of the little girl and her friends singing along while watching Rodrigo, 21, perform onstage.

Ashlee shares Jagger and her youngest son, 3-year-old Ziggy Blu, with husband Evan Ross. She also has a 15-year-old son, Bronx Mowgli, with her ex-husband Pete Wentz.

The mom of three regularly shares photos of her blended family on social media. About a week before the outing to the concert, Ashlee posted a carousel of summer highlights on Instagram.

"A summer to remember ✨," she captioned the post full of snapshots of the Simpson-Ross family posing with loved ones.

Jagger appeared to be jumping while suspended in mid-air in one adventurous photo in the set.

The little girl blew on dandelions with Ziggy in a video in the carousel, and posed in a picturesque location in a sweet snapshot.

In July, Ashlee posted a carousel of photos taken from a family trip to Hawaii, featuring her crew posing with family and friends on the beach and on a golf cart.

In an exclusive interview with PEOPLE earlier this month, Ashlee shared the secret to keeping her and Evan's 10-year marriage strong amid their busy schedules.

"I mean, we love each other," she said. "I think the secret is that we have grown together. And I think that if you can grow together and watch as we all change or evolve and stick together, that's probably the key to it all."
