Bobbi Kristina Brown marked her first birthday since the death of Whitney Houston

Bobbi Kristina Brown has marked her first birthday since the death of her mother Whitney Houston.

Bobbi Kristina Brown, the only child of Whitney Houston – whose lifeless body was found submerged in a bath tub at her Beverly Hills hotel suite on February 11 – turned 19 on Sunday and saw in the occasion with her close family.

A source said: ”Bobbi is now with the family and going through the grieving process just with them.”

Bobbi Kristina – whose father is Whitney’s ex-husband Bobby Brown – had to be hospitalized following Whitney Houston’s death, and went missing on the day of the funeral.

But an insider reveals that Bobbi Kristina Brown has started to show signs of improvement since bonding with her maternal grandmother, gospel singer Cissy Houston.

The source told US Weekly: ”[They] have been getting along a bit better. She really needs her own space right now to heal, and Cissy knows that.

”Cissy has a team of people helping her through this … right now, the goal is to make her feel special and loved.”

Meanwhile, Michael Jackson’s sister LaToya has weighed in on rumors that Whitney Houston has a secret fling with her brother Jermaine in the 1980’s, while he was married to first wife Hazel Gordy.

During an appearance on American chat show “The Talk”, LaToya Jackson said of her brother Jermaine: “He has admitted that they had an affair.”
