Bella Swan and Alice Cullen

I've always liked the relationship between Bella and Alice in the "Twilight" series. Alice is very friendly (for a vampire), and is quite eager to be friends with Bella and to welcome her into the Cullen family. They quickly grow to like each other and become like sisters, which is nice, as Bella never had any sisters and Alice lost touch with her human sister many years earlier. Alice is the maid of honor at Bella's wedding to Alice's brother, Edward. In the films, Ashley Greene plays Alice and Kristen Stewart plays Bella.
