Legend took to the piano to perform Houston's 1986 single, "The Greatest Love of All," which was followed by Sparks' moving rendition of "I Will Always Love You." Her version easily rivals that of Jennifer Hudson and Glee's Amber Riley.
Sparks performance brought the crowd to their feet and Bobbi Kristina to tears. After accepting the Millennium Award on her mother's behalf, she expressed how important the fans have been throughout this difficult time.
''I really want to say thank you to everyone who supported us through it all. Not just from when it was good but when it was bad, too. Thank you for showing that much love, because she deserved it... I'm just blessed to have been in such an incredible woman's life. There will never be another one, ever.''
As for the rest of the show, Adele cleaned house. The soulful Brit scored 12 wins including Top Artist, Top Billboard 200 Album and Top Alternative Song.
