Bobbi Kristina Brown and Nick Gordon at Grammy Salute to Whitney Houston

Bobbi Kristina Brown swapped her sapphire and diamond sparkler for a pair of stacked rings on Thursday night, as music’s biggest names gathered to pay tribute to Whitney Houston in Los Angeles.

Bobbi Kristina brown, 19, sat stoically through the We Will Always Love You: A Grammy Salute to Whitney Houston at the Nokia Theatre L.A. Live, where Jennifer Hudson, Britney Spears and Usher were among those on hand to give tear-jerking music tributes.

The teenager wore a bodycon red dress for the occasion – her hair coiffed in loose curls around her shoulders.

Bobbi Kristina Brown smiled bravely and clasped Nick Gordon’s hand from time to time, undoubtedly glad to have him there as her support.

Eyes, however, were drawn to the huge bauble on her left hand.

The stacked pair of rings were noticeably different than the jewellery Bobbi Kristina Brown flashed to family members in a newly-released promo for reality show The Houstons: On Our Own, in which she announced their engagement.

It remains unknown if the jewellery is a keepsake from her mother, or a gift from Nick Gordon.

The teenager has in the past been seen wearing her mother’s jewellery in the wake of her passing.

Bobbi Kristina Brown has meanwhile filled her time with minor acting roles and filming her family’s Lifetime reality show, The Houstons: On Our Own.

Viewers can tune in to see how the family drama unfolds when The Houstons premieres on Lifetime on October 24.
