Lupita Nyong'o took home the best supporting actress Oscar  for 12 Years a Slave and gave one of the most heartfelt speeches we've heard in quite a while. After thanking her brother for being her best friend, she said, "No matter where you're from, your dreams are valid." Oh, Lupita. We're sad for fellow nominee Jennifer Lawrence , but so, so glad that Nyong'o won. Watch her speech and hold back your tears.
