She'll always love her.

Bobbi Kristina Brown seized the opportunity at Sunday's Billboard Music Awards in Las Vegas to thank the millions of fans still grieving the death of her mother, Whitney Houston, back in February.

Chart-topping singer Houston (48 when she passed away Feb. 11 in Beverly Hills) was the posthumous recipient of the Millennium Award, with Whoopi Goldberg introducing two touching tribute performances: John Legend, who sang "The Greatest Love of All," and Houston's Sparkle costar Jordin Sparks, who sang "I Will Always Love You."

Bobbi Kristina, 19, was moved to tears during Sparks' cover of her mom's hugest hit. But she was calm and poised when she and her aunt, Patricia Houston, ascended to the stage to accept the award.

"I just want to say thank you to everyone who's supported us through it all. Not just from when it was good, but when it was bad, too. Just everything," said Bobbi Kristina, who famously struggled in the wake of her mother's shocking passing.

"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, never, and I thank you, all of you, fans, everyone, thank you so much."
