The singer and entrepreneur shared a bunch of pictures from the trip on social media, simply captioning the memories, “Aspen š.” In fact, it wasn’t just a trip with Simpson, her husband Eric Johnson, and their three kids, Maxwell, 10, Ace, 9, and Birdie, 3, as it looks like Simpson’s sister, Ashlee Simpson, and her family joined as well. Ashlee is married to actor Evan RossĀ and they have two children together, Jagger, 7, and Ziggy, 2. Ross also co-parents Ashlee’s son Bronx, 13, who she had with ex-husband Pete Wentz.Ā All three of Ashlee’s kids appear in Simpson’s photos with their cousins, clearly having a great time on vacation. In one of the photos, little Birdie sits on her dad’s shoulders in a stylish leopard-print snowsuit, while another shows Ashlee’s youngest, Ziggy, all decked out in snow gear and ready to go. One other picture in the bunch shows most of the cousins together, with Bronx, Maxwell, Ace, and Jagger all standing together, while Ziggy sits in a stroller in front.Ā Simpson’s followers loved seeing a bit of her Aspen trip, with one person commenting, “š„š„š„š„love Aspen! Wishing you guys a Merry Christmas!” “Your kids are happy and very loved. It shows. ā¤ļø,” another wrote. Neither Ashlee nor Ross appear in Simpson’s most recent photo drop, but Simpson previously shared a couple more posts with photos on her Instagram. The first bunch includes a cute photo of the sisters, and one adorable shot of Ashlee and her niece Maxwell fast asleep on the couch. Simpson also posted a glam skiing shot in which she rocks a bright red snowsuit and a fur hat, with some big sunglasses to protect from the sun’s reflection off of the snow. Paris Hilton commented on these photos with a few emojis, writing, “šā¤ļøā¤ļøā¤ļø.”
