"My baby she was The LOL Doll THRILLA," Kardashian West tweeted Saturday, along with a smiling emoji with hearts for eyes.
The post also included a video from The Wests Twitter feed, a fan page devoted to the famous family, which included footage of North walking down an outdoor runway, while wearing a red leather jacket and skirt, sunglasses, white socks and black shoes reminiscent of the ensemble Michael Jackson had on in his classic music video "Thriller."
E! News said Kardashian West was spotted holding up her phone and filming North in the LOL Surprise! fashion show in Pacific Palisades near Los Angeles.
North is the oldest of the couple's three children. The Wests are also the parents of 9-month-old daughter Chicago and 2-year-old son Saint.
