It’s been a rough 3 months for 19 year old Bobbi Kristina, but she found the strength to honor her famous mom Whitney Houston, last night at the 2012 Billboard Awards.

Details below…

Whoopi Goldberg introduced the teen who was escorted onto the stage by her adopted brother/rumored fiance’ Nick Gordon after she received a supportive kiss from him.

Aunt Pat Houston also joined Bobbi K onstage during her emotional delivery.

I just 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, to just everything.

Thank you so much for showing that much love ’cause she deserved it. I’m just blessed to have been in such an incredible woman’s life.

There will never be another one, ever.

John Legend and Houston’s “Sparkle” co-star Jordin Sparks honored the legendary superstar with a musical tribute.

Legend sang “The Greatest Love Of All” while Sparks sang Houston’s classic, “I Will Always Love You.”
