With the announcement of her divorce from husband David Foster and questions about her Lyme disease diagnosis this season of The Real Housewives of Beverly Hills, some may say that it's been a tough December for Yolanda Foster. However, Yolanda was all smiles this Christmas as she and her three children — Gigi Hadid, Bella Hadid, and Anwar Hadid — were all together again for a family vacation in Aspen last week. "The best thing to hold onto in Life is each other," Yolanda wrote in the caption to a family photo on Instagram. "Merry Christmas from our family to yours xoxo."

This isn't the first time the family has vacationed in Aspen, as the adorable throwback pic of Yolanda and Gigi below shows.

Yolanda also seems more optimistic about her health lately, even though we've seen her have good and bad days this season of RHOBH. "I may not be there yet but I am a lot closer than I was last Christmas," she wrote on Instagram, where she also shared several other photos filled with inspiration and gratitude this holiday season.

Yolanda's health seems to have improved since we saw her struggle with her illness on RHOBH, like in this heartbreaking moment from earlier this season in the clip, below.
