We all fell in love with Isla Fisher back in the '90s when she played Shannon Reed on Home And Away.
Since then, Isla has become a very successful actress in Hollywood but we could still pick her out of a line-up of famous actresses... right?
Apparently, some Americans can't tell the difference between Isla and Acadamy-Award winning actress Amy Adams!
Whilst chatting to Jimmy Kimmel on his late-night talk show, the Aussie actress mentioned a few awkward instances where she had been mistaken for Amy...
"I remember one time I was at this fancy Hollywood party, I've seen you there, the Vanity Fair party and I was there, excited, all dressed up at the bar and schmoozing with showbiz types.
"Then the crowds parted and there was Lady Gaga and she was heading right towards me!
"And she says, 'thank you, your performance in American Hustle, Amy, was...'
"And I'm thinking 'oh my gosh, it's Lady Gaga, I love her so much, I don't want to tell her the truth."
So poor old Isla just said thank you and once the REAL Amy Adams arrived at the party, she did the most Aussie thing ever!
"I look over her shoulder and there's Amy Adams walking into the party!
"So I'm like, 'there's Isla Fisher, she's not even nominated for anything, why is she here?' "
But seriously, Isla is mistaken for Amy all the time and so, she decided to record a PSA telling showing everyone the key differences between her and her Oscar-winning doppelgänger.
First, Isla would like everyone to know that "Amy Adams has auburn red" hair and her hair "is light auburn red".
She then also mentioned that not only does she get mistaken for Amy, she also gets mistaken for Jessica Chastain!
It never ends!
Plus, Isla is Australian!
She has an Australian accent!
It's okay Isla, we'll never confuse you with anyone else!
