WATCH: The Billboard Awards Tribute to Whitney Houston.
Whoopi Goldberg introduced the tribute, then John Legend sang "The Greatest Love of All" which was followed by a "I Will Always Love You" performed by Houston's Sparkle co-star, Jordin Sparks.Bobbi Kristina wiped away tears from her eyes during the performances, but after she took the stage to accept the award on her mom's behalf, she was very composed.
"I really want to say thank you to everyone who supported us through it all," the 19-year-old said, with the late singer's manager and sister-in-law Patricia Houston by her side.
"Not just from when it was good but when it was bad, too. Thank you for showing that much love, because she deserved it," Bobbi Kristina continued. "I'm just blessed to have been in such an incredible woman's life. There will never be another one, ever." Watch below:
