Get ready to smile.

TGIF, right? And what better way to head into the weekend than by looking back at some viral stories that melted our hearts this week in our latest installment of Feel Good Friday, our new series that sets out to end the week on a positive note and highlight stories you might've missed but definitely will want to check out. 

In this week's offering, we're highlighting some heroes that are helping to fight the devastating wildfires that have been spreading across Australia for months, including a koala-saving dog with his own inspiring backstory that seems destined to be turned into a hit Disney movie, and a group of U.S. firefighters whose arrival in Australia went viral. 

Plus, a man pulled out all the stops to deliver a fairy tale-worthy proposal for his longtime Disney princess-loving girlfriend, and a major A-lister helped save a man's life while on vacation. 

Here are the stories that will put a smile on your face as you head into the weekend...
