The 41-year-old model says she is particularly uncomfortable with taking pictures of herself to post online, reported Femalefirst.
"I don't have a relationship with social media at all. I don't know how to take a good selfie. I'm not good at them," Moss said.
While she isn't interested in social media, Moss - who has 13-year-old daughter Lila with ex-boyfriend Jefferson Hack - admitted she does have an Instagram account so she can "spy" on people and keep her knowledge of pop culture up to date.
