The stunning supermodel got a tattoo of a cross on her finger so she could always show her devotion to God, she explained in the September issue of Elle. 

“I was at a photo shoot and I was wearing a cross necklace that my mom bought me, and somebody made a joke like, ‘Why are you wearing a cross?  Like you would be religious.’  And then they took [my necklace] away,” Upton told the magazine. “ I was really affected by that.  The whole thing made me realize that I do want [a cross] with me, at all times.”
