Heather Hills is one of the main antagonists in the third film. She is a teenage girl in Rodrick Heffley’s grade and the older sister of Holly Hills.

Heather has a huge resemblance of her sister Holly Hills. Heather has long hair that is sometimes tied in a ponytail and wears pitch black earrings in both of her ears.

Rodrick Rules
In Rodrick Rules, Heather babysits Rowley Jefferson while his parents were gone. Greg Heffley harbors a crush on her. Whenever Rowley's parents go out, Greg would go to Rowley's house at 8:00 PM and splash on Rodrick's cologne to make sure he makes a good impression on her. She was later replaced by Leland, which surprised Greg and started complaining how his parents needed to keep Heather. She is also mentioned by Holly. Holly shows that Heather is a female version of Rodrick, like how Greg is possibly Holly's female counterpart. Also, she appears in Rodrick's old yearbook.

Dog Days
In Dog Days, Greg has a crush on Heather and Holly Hills. He thinks of getting good with her because he wants to have a high school girlfriend before school starts. He finds out she is a lifeguard at the pool by looking into one of the family's summer albums. When the family went to the pool, Greg went into the bathroom and started doing push-ups and other exercises so his muscles pop-up then he goes near her chair. Whenever a kid does something bad, Greg spoke up before Heather could say anything, thinking it will impress her. But then, a kid vomited and Greg didn't clean up, which was the only time when she paid attention to Greg because she was expecting him to say it. The other day when Greg came there, he went near her chair and asked Susan Heffley take a picture of him there. Susan was about to take the picture, but she got a phone call from an old friend. By the time she takes the photo, Heather left so Greg ended having the photo taken with another Lifeguard. Greg then realized she is going to college, he thought long-term relationships don't work so he scrapped his plan of getting good with her.

Film series
Heather is only briefly mentioned in Diary of a Wimpy Kid: Rodrick Rules (film). She is described by Holly Hills as a female equivalent of Rodrick Heffley. As Heather is a valley girl, she freaks out over the littlest girl things and doesn't care about anything but herself, as shown in Diary of a Wimpy Kid: Dog Days (2012 film) where she says for Holly to get in the car and says she doesn't care if Holly is signing Greg's yearbook. She later appears in the third film as a love interest of Rodrick and one of the main antagonists, acting like a bigger jerk than Rodrick, being a stereotypical self centered teenage girl. She first shows up to pick Holly from school, and when Rodrick tries to flirt with her, she runs over his foot. She naturally goes to the same Country Club as her family, getting a job there as a life guard. She acts rude to almost everyone, including her own parents, only thinking about her upcoming sweet sixteen and even ignores when Rodrick pretends to drown to get her attention. Greg manages to get her to hire Loded Diper for her birthday. While there, it falls into ruins when she angrily reacts to Rodrick's rock cover of Justin Bieber's "Baby." Just then, Rodrick accidentally knocks down the ice sculpture, which causes her to get angry and tries to hit Rodrick. But, he ducks down and Heather hits the chocolate fountain, which causes it to spray all over Heather and Madison. All the guests left her party. Greg apologized to Holly, but she said she was happy and that she thought that Heather fairly deserved it.
