From LA to La Dolce Vita

When Sydney Sweeney promises a family vacation, expect the unexpected! The 'Euphoria' sensation turned a dreamy Italian getaway into a horror set experience for her grandmothers. "I flew them to Italy and they got to come visit me on set," Sweeney gushed on the 'Today Show.' Picture this: Granny in a habit, praying she won't get the heebie-jeebies!

Sweeney's grandmothers, who had never ventured to Europe, were in for the thrill of their lifetime. "My Grandy's dream was to go to Italy," Sweeney revealed to Jimmy Fallon. And what a dream it became – from LA's glitz to Italy's old-world charm, with a twist of terror!

The 'Immaculate' plot thickens with Sweeney as "Sister Cecilia," whose holy mission turns hellish amidst the Italian countryside's creepy convent. "It’s a challenging character," she admitted, hinting at a controversial climax that's sure to stir up some serious chills and chatter.

Sweeney's not shying away from the divisive ending. "I like when movies or endings create a discussion, a debate," she declared, prepping her audience for a "wild ride." With co-stars like Simona Tabasco and Álvaro Morte, "Immaculate" is shaping up to be the talk of Tinseltown.
