In March 2020, Nicole showed off a tiny neck tattoo on Instagram, which simply reads, "MOON." It's unclear what the tattoo means, but she did use a moon emoji in a February 2020 IG post (which has since been deleted) that seemingly alluded to Brad. "Missing my strolls with my Love 🌙💥," she captioned the photo, with the location tagged as Los Angeles. Could the tattoo be a nod to the actor? Your guess is as good as ours!
