The pair spent the day taking selfies and chatting with patients, and their visit was a big hit.
“Today we received a surprise special visit from a couple of people you might recognize,” the hospital posted on their Facebook page alongside a slideshow of photos. The post thanked them for “bringing joy and laughter” to the children.
Cyrus, 24, also shared snaps of the special day on Instagram.
The pop star was dressed in a 1960s-inspired flower-power dress, with pink knee-high boots and a fluffy sweater.
Her attire was a nod to her Happy Hippie Foundation, which she launched last year to help young people fight injustice.
On Christmas Day, she shared a message to social media, saying the foundation was “what I am most thankful for this year because of the purpose it gives me. Without it I would feel so lost and useless on this planet.”
She also encouraged people to give the “gift of love and acceptance this year to not only their own family but those around the globe who don’t get everything they wished for due to life’s unfair circumstances!”
