Mary-Kate and Ashley Olsen turn 27 today -- and while they've been living more separate lives lately, they still look exactly the same!

Mary-Kate has been spending all of her time with her 42-year-old beau, Oliver Sarkozy, and showing major PDA at basketball games, while Ashley's stayed out of the spotlight with the exception of major fashion events like the Met Gala.

The sisters continue to do great things within in their own respective fashion lines -- but we miss seeing the blonde beauties on the silver screen!

How great were their flicks like "New York Minute" and "When in Rome"? But our favorite Olsen TV moment has to be playing Michelle Tanner from "Full House."

Nevertheless, the famous twosome have fared better in Hollywood than many of their fellow child stars (a la Lindsay Lohan and Amanda Bynes), and we're excited to see what they do next.
