In honor of Charlie's special day, we decided to take a look back at all of the girls this heartthrob has been linked to since stepping into the spotlight. Of course, we all know that he may or may not have had a fling with Selena Gomez, BUT did you know that he got turned down by another leading lady?!

Charlie hasn't been in a serious relationship while under the public eye just yet, but any of these girls he was rumored to be dating would have been a perfect match. They would be lucky to have such an awesome guy like him!
