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.
