Mind = blown.

If you thought that Jennifer Garner and Mark Ruffalo were the only big stars to come from the noughties hit 13 Going On 30 you'd be wrong, very wrong. In fact, the film also starred two other massive stars (one who's an Oscar winner) and the other who has starred in one of the most popular American series of the past 10 years and is also dating a famous model. The pair had small cameo roles in the film, ones you'd miss if you weren't eagle-eyed. Both Brie Larson and Ashley Benson starred in the 2004 film as members of the oh-so-popular girl clique "Six Chicks". Yes, really. Brie Larson starred as "Six Chick #3" (to the far right) while Ashley Benson starred as "Six Chick #2" (next to her in pink). What's even better is that Mark Ruffalo who plays Matty in the film never even knew that he starred alongside Brie in the flick. While on the red carpet for Avengers: Endgame, a film both Larson and Ruffalo star in, the 51-year-old couldn't believe that Brie starred alongside him. Pretty priceless and now we've such an urge to watch the movie for the 17,000 time.
