It was a night of tributes at the Billboard Music Awards on Sunday.
The evening’s most emotional moment came during a tribute to the late Whitney Houston. While Jordin Sparks performed the singer’s iconic hit “I Will Always Love You,” Houston’s daughter, Bobbi Kristina Brown, broke down in tears before taking the stage to accept the Millennium Award on her mom’s behalf.
“I really want to say thank you to everyone who supported us through it all,” said Brown, who stood alongside Whitney’s manager and sister-in-law Patricia Houston. “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.”
