The 38-year-old accidentally flashed her underwear as she strolled along the street in a stunning backless dress at the premiere on Thursday, reports aceshowbiz.com.
Scherzinger, who plays Penny Rivera in the TV remake of the iconic 1980s dance film, was spotted wearing a cream floor length dress with a split slashed across the mid-thigh and a plunging neckline.
However, she failed to notice that her risque gown had ridden up, exposing her cream-coloured knickers.
After attending the event, she headed to an after-party at TAO nightclub.
It's not the first time Scherzinger has suffered a wardrobe malfunction. Earlier this year, she flashed her lower back as she bent down to get into a car that was waiting outside the venue of London Fashion Week.
