Justin is related to Avril Lavigne and Ryan Gosling!
Biebz is a 12th cousin to Avril and an 11th cousin once removed to Ryan.
"Their ancestry link dates back all the way to 400 years ago when some of the earliest settlers came to Quebec. Their common relatives are Mathurin Roy and Marguerite Bire who were born in the early 1600s in France, got married in 1637, and moved to Quebec."
Thanks to Wambie girl Lily for sending this in!
