Dakota Johnson and Chris Martin get matching infinity tattoos

Chris Martin and Dakota Johnson have been dating for only about a year, but things are looking serious: The Coldplay rocker and Fifty Shades of Grey star just got matching tattoos. Johnson debuted her new ink over the weekend at the Venice Film Festival, where she is promoting her new film, Suspiria. While waving to photographers, an infinity sign with “xx” within it was visible below her left elbow. Martin stepped out in Los Angeles days earlier sporting the same tattoo on his right forearm.
