Beyonce Knowles Carter opened the event with an emotional rendition of her song, "XO."

The late night comedian got incredibly choked up while speaking at the event, saying, "I've been trying to come up with something positive to take away from this and it was hard because there isn't much. But the best thing I think I was able to come up with is this -- gratitude. It seems to me that all we can do is be grateful for the time we had with them and the time we have left with each other."
Women's basketball stars Sabrina Ionescu and Diana Taurasi spoke at the event.
