You may know the SUPER talented Lauren Spencer-Smith from her hit singles 'Fingers Crossed' and 'Flowers' but we're getting to know her on a WAY deeper (and more personal ) level in a game of Read Receipts, a.k.a. phone truth or dare . Lauren told us EVERYTHING from the phone numbers she knows by heart , to the weirdest thing about her (hint: it involves ketchup ) and even told us a story about the dumbest thing she's ever done ! Watch MORE Read Receipts HERE and see if your FAV celeb has shown their cellphone to Seventeen https://www.youtube.com/watch?v=Uhn8qpGh6uU&list=PLunx6D_le-dK0S0Dbp6w_XnTTHvrUJtqv
