Thanks to some great work from Eck, he found out more on whether Logan Lerman’s Instagram is fake. Here’s what he had to say:
“Ok C: first… the photo “Logan” uploaded is from a fan (x) aaaaand the real instagram account is loganlerman19 as you can see, Dean Collins (his best friend) tagged him here… so the account is fake C: the photo’s from a fan and your whole life is a lie n_n”
In other words, yes Logan Lerman’s Instagram account is fake! Thanks so much for the help, Eck!
