The 17-year-old photographer and model was spotted at the award ceremony on Wednesday evening (February 22) at The O2 Arena in London, England.
Brooklyn broke his collarbone in the accident and has been wearing a sling around his arm.
He kept the injury covered up with an over sized coat while walking on the red carpet.
Brooklyn seems to be having a great time at the show and even went live on Instagram to stream some of the show!
Be sure to tune into the live stream of the show while it airs tonight!
