Robin Gibb, Donna Summer and Whitney Houston have all been remembered at the Billboard Music Awards which saw Adele win 12 trophies.
Early in the show, there was a moments pause to remember the former Bee Gees singer who died on Sunday after a long battle with cancer.
News of Gibb's death had been announced shortly before the awards took place.
Hosts Julie Bown and Ty Burrell said: "Just a little over an hour ago, we received the very sad news that the music world lost another legend.
"So we wanted to take a moment to pause and remember Robin Gibb. His voice and the Music of The Bee Gees will live on forever."
There were also tributes for Donna Summer with Natasha Bedingfield singing the Disco Queen's signature hit Last Dance while Cee Lo Green and his hip hop group performed Beastie Boys' Fight For Your Right as a tribute Adam Yauch who passed away earlier this month.
But the biggest tribute of the night went to Whitney Houston with John Legend singing Greatest Love of All and Jordin Sparks performing I Will Always Love You against a backdrop of photographs of Houston.
The singer, who died in February, was posthumously given the Millennium Award.
Houston's daughter, Bobbi Kristina Brown, accepted the gong from actress Whoopi Goldberg alongside the singer's sister-in-law, Patricia Houston.
In a poignant speech, she said: "I just really want to say thank you to everyone who supported us through it all. Not just from when it was good, and when it was bad, to everything.
"Thank you so much for showing that much love because she deserved it. She did.
"I'm just blessed to have been in such an incredible woman's life. There will never be another one, ever. And I thank you, all of you, the fans, everyone, thank you so much."
Grammy award winner Adele continued her winning streak less than a week after receiving two Ivor Novello awards.
The British singer, who was absent from the event, received Top Artist, Top Pop Album for 21 and Rolling In The Deep won Top Hot 100 Song.
Other winners at the awards included LMFAO who picked up six trophies.
Coldplay were named Top Rock Artist and Top Alternative Artist while their album Mylo Xyloto got Top Rock Album and Top Alternative Album.
