Holly Hills

Holly Hills is Heather Hills's little sister, and according to Greg, one of the most popular girls in his grade.

Overview
She has made an appearance in the original and The Last Straw, and is briefly mentioned in the credits to one of Greg's many comics in Rodrick Rules. She was once Greg Heffley's crush, and he tried to do everything to make her notice him, until it failed when she mistakenly called him Fregley, which Greg took as an insult. Later, while signing the yearbooks, she writes a note to Greg saying that "He's Ok". She had a slumber party in this book.

She likes Rowley Jefferson, because she thinks that he is "cute" and prefers his silliness over Greg's flirting. This is true since she wrote a note in Rowley's yearbook saying that he's funny and cute. Greg, however, attempts to break this by writing a note to Holly, but what it has caused to her remains unknown so far.

She does not make an appearance in Dog Days, but is mentioned by Greg when he sees her sister Heather Hills. It appears that her sister works as a lifeguard at the Town Pool.

Holly is never mentioned in The Ugly Truth, but when Greg shows online pictures of people, two of the pictures looks like pictures of Holly Hills' slumber party from book three. In another odd occurrence, when they do the egg parenting assignment & the Lock-In, a girl that looks exactly like Holly appears.

Holly also appears in the film adaptation of Diary of a Wimpy Kid: Rodrick Rules, set to debut sometime in 2011.

Appearance
Holly's appearance is thought to be overly attractive, the way Greg depicts her. She is colored black and white, like everybody else in the book. Her notable features include an earring, an ear with an arrow depicted as the insides, and a skirt that covers her knees.

Personality
Not much is known about her personality, since Greg rarely talks to her. She thinks of Rowley as cute, which disgusts Greg, and tends to be aloof, however.
