How did we only find out about Ryan Gosling's hot sister until now??
Ryan took his sister Mandi Gosling with him to the Oscars, and everyone is seriously losing their sh*t over how much of a babe she is.
At first, people were wondering why he had turned up with this mysterious blonde woman on his arm (and not Eva Mendes), but it was quickly revealed that it was his sister *sigh of relief*
