The "Come & Get It" singer shared an adorable snapshot on Instagram, posing with her baby sister Gracie.
"Sissy," the pop starlet wrote, along with the candid photo of the tiny tot laying on top of her with a giant grin.
After Selena enjoyed a fun afternoon with Gracie, the 21-year-old spent some time with her girlfriends on ladies night.
"Ladies being ladies. Ladies night," the brunette beauty captioned a photo with pal Zooey Deschanel and another friend at Soho House in West Hollywood.
We're happy to see the songstress is having some fun, after she cancelled her Australian tour to focus on herself.
"My fans are so important to me and I would never want to disappoint them," she said in a statement. "But it has become clear to me and those close to me that after many years of putting my work first, I need to spend some time on myself in order to be the best person I can be."
