It was supposed to be her late mother's night.

But US actress-musician Bobbi Kristina Brown, the 19-year-old daughter of late singer Whitney Houston, ended up stealing the show when she appeared at the Los Angeles premiere of Houston’s final movie, Sparkle, with boyfriend and adopted brother Nick Gordon.

This was the couple’s first red carpet debut after publicising their relationship shortly after Houston’s death in February.

Before the event, Brown tweeted: “Off to the premiere! Glammed and all! Time to walk this carpet & rep mommy like she would want me too (: god bless u all ! nickdgordon enjoy!”
