Duff joins a large crowd of celebrities already quite active on the app. Most share revealing tidbits from their day-to-day lives like working out, hanging with non-famous friends, and behind-the-scenes action at work.

She's already learned how to play with the filters.
She entertained herself while waiting for a doctor's appointment by watching her Snapchat friends grow.
And, as stars do, she Snapchatted her glam squad prepping for an event.
