Ross shared a sweet Instagram snap of the family of four on a ski trip

Families that ski together, stay together, right?

Ashlee Simpson and Evan Ross took to the mountains recently with their baby girl Jagger Snow and Bronx Mowgli, Simpson’s son with ex-husband Pete Wentz.

Ross, 27, shared an adorable Instagram snap of the little clan, including a few hashtags in the caption: “#Aspen. #family #skiing #memories.”

The pair welcomed daughter Jagger in July and previously told PEOPLE about Bronx’s big brother skills.

“Their age difference is really sweet. Bronx is such a good big brother. He’s a pro,” Simpson, 31, said. “It makes home so awesome.”

Ross added that Bronx carries his little sister and “makes sure he watches her all the time.”

Simpson said that at just 4 months old, Jagger isn’t afraid to exercise her power as the baby of the family.

“She definitely knows what she wants and will let you know,” Simpson said of her daughter.
