Greta Gerwig's Barbie is now playing in theaters, and the Mattel film features a bunch of fun easter eggs. There may even be some little nods you missed if you've only seen the movie once. This week, TikTok user Ivan Mars took to the social media site to share a video about a pretty cool Bratz easter egg. MGA Entertainment's Bratz dolls came onto the scene in 2001 and managed to outsell Barbie three years later. In fact, there have been legal battles between MGA Entertainment and Mattel over the years thanks to the dolls. Turns out, Barbie pays homage to their rival by modeling Ariana Greenblatt's character and her friends after the original Bratz.
