Taylor Swift caused a stir among fans with her unеxpеctеd appearance at the New York premiere of her friend Emma Stone’s latest film, “Poor Things.”

Arriving in a chauffeured black SUV, the 33-year-old singer was accompanied by security as she made her way to the venue on Wednesday. Swift looked stunning in a glamorous black fur coat and her trademark red lipstick, complemented by her Ԁirty blonde hair cascading in loose tendrils over a silky black midi dress.

Wearing tall open-toed heels that showcased her scarlet pedicure, revealed as TIME’s Person of the Year, Swift strutted confidently. She carried a gleaming hardshell purse with a gold handle, and her ruby pout was accentuated by winged eyeliner and a touch of warm brown shadow on the lids.

Lucky fans on the sidelines captured photos of Swift’s surprise arrival. Emma Stone, looking exquisite in a plunging gown, was asked about Swift on the red carpet. Swift had recently released the vault song “When Emma Falls in Love,” speculated by fans to be about Emma’s whirlwind romance with her now-husband Dave McCary.

When asked about the song, Emma responded coyly, “You’d have to ask her.” She also remained elusive about whether the “Wildest Dreams” hitmaker would be present to support her at the premiere, stating, “We’ll see,” to ET reporter Rachel Smith.
