She left jaws dropping on the red carpet earlier in the evening.
Sydney Sweeney kept the glamorous night going on Monday, celebrating the premiere of her new film, The Housemaid, alongside co-star Amanda Seyfried.
The 28-year-old actress, known for being outspoken, wore a short white dress while enjoying time with the 40-year-old star of Mean Girls. They were celebrating before their new film comes out.
Sydney started the party in a dramatic, white ball gown with a tight waist and low neckline, then fully embraced the fun with a change of outfit.
She changed into a short, strapless dress covered in flower details for the after-party, a fun contrast to her red carpet outfit. Amanda, however, kept the same look she wore all night.




Sydney looked stunning at the party, and her stylish mini dress perfectly showcased her figure.
She continued her signature style with a white outfit, bold red lipstick, and striking eye makeup, creating a perfectly glamorous appearance.
Amanda looked equally stylish in a sparkly, knee-length dress. It featured a fitted, ruched waist, a strapless design, and a daring leg slit.
I’m so excited about Sydney’s new movie! She plays Millie, a maid who takes a job living with this incredibly wealthy woman – Amanda Seyfried is amazing as her. As the story unfolds, Millie starts uncovering all sorts of dark and twisted secrets about the family she works for, and it’s completely captivating!
The premiere also included appearances by their co-stars, such as Brandon Sklenar, and other celebrities like Awkwafina and Skai Jackson.
Amanda and Sydney have become good friends while promoting their project, and their connection was especially clear during a funny lie detector test they did last week.




During a lie detector test for Vanity Fair on Thursday, Amanda directly asked Sydney if she had breast implants.
An interviewer directly asked the actress if she’d had breast augmentation surgery. Amanda, age 40, bluntly asked, ‘Are your breasts real?’ and Sydney immediately responded, ‘Yes.’
Amanda then asked if she’d ever had plastic surgery, and the actress firmly replied, “No, I’ve never had any work done, anywhere.”
The lie detector test showed she was being truthful. This situation simply brought attention to an issue Sydney has had to deal with many times during her acting career.



In a recent interview with Allure, she revealed she’s never had any cosmetic procedures, admitting she’s afraid of needles. She also explained that it’s unfair and inaccurate to compare childhood photos of herself to her current, professionally styled red-carpet appearances.
The actress pointed out that it’s unfair to compare a picture of her as a child to a recent, professionally taken photo. She explained that she’ll naturally look different after so many years, and added that people on social media are often unreasonable.
Sydney playfully mentioned she wouldn’t change a thing, even admitting she still has a little asymmetry from a wakeboarding accident she had as a child. The accident, which happened near her left eye, required 19 stitches.
