We've seen a lot of good looking siblings in our day, but this celebrity brother and sister might take the cake for the hottest.

Amy Morris (ring any bells yet?) posted this photo on Instagram and we're not sure if we have a bigger crush on her, or her big brother. That's right, this stunning lady is none other than Julian Morris's (Wren Kingston) younger sister.

Amy is the Pretty Little Liars actor's only sibling and the two Brits grew up in London. With such gorgeous genes, we can only imagine what their parents look like! After all, Julian and Amy's mom and dad are Zimbabwean and South African, respectively, so it's not surprise they had such beautiful children!

Are you surprised that this is Julian's sister, or do you think it's obvious by their looks? Let us know in the comments below!

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
