The "Stay With Me" singer and his sisters Mabel and Lily Smith took a family trip to the tattoo parlor on Christmas Eve (how did they even find one that was open?) and they all got matching ink.
"Me & my sisters new tattoos," he captioned the photo below, where they showed off a Roman numeral three on the inside of each of their wrists. Mabel posted the same pic with the caption "happy days."
We're not sure if the three has some special meaning to them or if they're like the three musketeers. Either way, we think it's super cool that they did that together.
Also during the trip, Sam got his finger tattoos touched up, but he's keeping that ink under wraps right now - no, literally, they're still all bandaged up!
Merry Christmas, Smith siblings!
