Barbie: A Fairy Secret (2011) on Netflix

Plot summary

At the premiere of her newest movie, Barbie is on the red carpet with Ken when her co-star Raquelle steps on her dress and rips it. Her stylists Carrie and Taylor mend it with magic, and a photographer named Crystal carries a picture of Ken back to Gloss Angeles. There she serves Princess Graciella tea mixed with a love potion and shows her the photo, and the princess falls for him at once. The following day at Wally's restaurant, where Barbie argues with Raquelle about the dress, Graciella and Crystal appear with two assistant fairies and seize Ken, and the portal closes before Carrie and Taylor can follow. The stylists admit that they are fairies, and warn that a human who marries one stays in their realm forever.
