In the heart of a chaotic family vacation, Diary of a Dirty Stepmother (2026) delivers a laugh-out-loud summer tale, combining humor, heart, and all the messiness of blended family dynamics. With a star-studded cast, including Jennifer Lopez, Jonah Hill, Awkwafina, and Zac Efron, this film not only promises plenty of beach fun, but also digs deep into the unpredictability of relationships and the secrets we try to bury under the sun.

Jennifer Lopez takes center stage as the glamorous yet tough-as-nails stepmother, Karen, who’s navigating her newfound role in a family full of chaos. She’s the one who has it all together on the outside, but behind her impeccable beach attire and perfectly managed hair, she’s juggling a juggling act between keeping her family together and controlling her own chaos. Lopez’s portrayal of Karen is sharp, witty, and packed with the kind of no-nonsense attitude that will make you root for her through every wild moment. She’s a woman who knows exactly what she wants – even if she has to deal with a series of ridiculous and sometimes cringe-worthy situations to get it.

Jonah Hill, playing the goofy stepdad Sam, is the perfect comedic counterpart to Lopez’s more put-together character. Hill brings his trademark awkward charm and relentless positivity to Sam, making him endearing even in the most challenging of situations. His performance is pure comedy gold, as he fumbles his way through family secrets, beach games, and miscommunication while trying to maintain some semblance of order. Hill has an incredible knack for blending the absurd with the heartfelt, making his character one of the most relatable and lovable of the film.
Then there’s Awkwafina, who steals every scene as Karen’s wild, fun-loving cousin, Lily. Armed with a water gun, a mischievous grin, and no filter, Awkwafina’s performance is a breath of fresh air in the chaotic family dynamic. Her timing and delivery keep the energy high, providing the perfect balance to the more serious moments in the film. Awkwafina’s humor adds a layer of unpredictability that makes every scene feel spontaneous and alive.
Of course, Zac Efron’s addition to the cast brings a dose of beachy charm that fits perfectly within the story’s lighthearted atmosphere. His character, Chad, is the easy-going surfer who’s more focused on perfecting his tan than dealing with the drama unfolding around him. Efron’s laid-back performance creates the perfect counterpoint to the frantic energy of the rest of the cast, adding a calming effect to the madness. His chemistry with the entire ensemble is natural, and his portrayal of Chad’s chill demeanor adds a touch of much-needed levity to the film.

As the family gathers for the much-anticipated beach party of the year, secrets begin to unravel in the most hilarious of ways. The film capitalizes on the absurdity of family dynamics, mixing slapstick humor with heartwarming moments that emphasize the importance of love, acceptance, and understanding in even the most unexpected relationships. The humor never feels forced, and while the characters are larger-than-life, their struggles are rooted in very real emotions—making their wild interactions feel relatable in their own way.
