"What did I do this weekend? Got some ink with my best friends," she captioned the photo collage, which showed Sarah and one of her pals mid-tattoo and then the finished products side-by-side on the right. She said there were three arrows, so we're not sure who the third arrow belongs to.
This is Sarah's second tattoo (that we know of!). The Modern Family star got a hummingbird behind her right ear back in November.
"The hummingbird, though it be but little, can travel great distances. It is a carrier of joy and lightness of being Independent and resilient; the hummingbird lifts negative energy from your life and shows you the perfect combination of playfulness and endurance," she explained in the photo caption.
Sarah's second tattoo is in the center of her upper back, while her pal opted to get hers on her wrist instead. We think it's kinda cool that they got the same tattoo to symbolize their friendship, but that they each opted for a slightly different design to fit their unique tastes.
Sarah certainly isn't the only celeb to get a friendship tattoo. Hilary Duff got a ghost tattoo with her best friend and Cara Delevingne and Jourdan Dunn got "DD" inked on their hips together.
