Bobbi Kristina Brown Sparkles at Late Mother Whitney Houston’s Last LA Movie Premiere

Bobbi Kristina Brown’s smile glittered bravely as she attended the LA premiere of her mother’s final film last week.

Whitney Houston’s daughter walked the red carpet with adopted brother/boyfriend Nick Gordon as Sparkle made its world debut at Grauman’s Chinese Theatre in Hollywood.

The 19-year-old had more than Gordon for moral support, however: grandmother Cissy Houston also attended the event.

Additionally, she had some surprise support in the form of the movie’s star – and her mother’s final co-star – Jordin Sparks.

Brown tweeted to the former “American Idol” winner before the premiere: “See you tonight mamacita ! I can’t wait . It’s gonna be tough, let’s try to CELEBRATE. love you Jordan”.

She added: “Time to walk this carpet&rep (represent) mommy like she would want me too (sic)”.

Afterwards, she tweeted: “2nite was incredible..! SPARKLE! JordinSparks &all the cast, I Thanku4makinitUNFORGETTABLE (sic)!”

The event was also attended by stars Derek Luke, Mike Epps and Cee Lo Green. Others showing their moral support included singer Christina Milian, actresses Amber Riley and Tika Sumpter, and R&B star Ray J, who dated Houston on and off until her death in February.
