TwitterThe Met Gala may be one of fashion's biggest nights but the celebs didn't seem to take things too seriously on the red carpet.
In fact, quite a few famous faces were seen photobombing fellow attendees on the steps of the Metropolitan Museum of Art.
Case in point? Cara Delevingne jumped behind Stella McCartney, Rihanna, and Reese Witherspoon during their group pic.
The model spread her hands out high in the air to make sure that she caught the camera's attention.
The group of well-dressed ladies flaunted their McCartney designs together for most of the night, but clearly Delevingne wanted to stand out among the rest!
The other photobomb was way more subtle and unintentional…
During an adorable snapshot of Blake Lively and Ryan Reynolds, Amber Heard can be seen in the background right in the middle of the shot.
But aside from the cameo from the future Mrs. Johnny Depp, all eyes were on Lively and Reynolds' red carpet PDA and stunning outfits.
The blond bombshell rocked a gorgeous sequined Gucci gown that not only fit her to a T, but matched flawlessly with the theme of the night as well.
The good looking couple rarely makes red carpet appearances, let alone together, so the night was a special occasion for many reasons.
