The daughter commemorates the special day of the late singer by posting some touching messages on Twitter.
The 21-year-old girl tweeted a touching message along with a photo of a small birthday cake to mark the occasion on Saturday, August 9, "#HappyBirthdaymommy ! #HappyBirthdayWhitney ! #AllAugustAllWhitney #iloveyou ! @nickdgordon @mwhitaker10 #Family."
Bobbi, whose father is "My Prerogative" singer Bobby Brown, also wrote a heartfelt tweet earlier that day, "GoodMorningWorld ! & AGrandBeautifulPhenomenalWonderful HappyHappyHappyBirthday2my amazingMommy! 2day is YOUR day, Iloveulady! @nickdgordon."
She continued the message on August 10, writing," Love is such a beautiful thing when it's #Real. #AllAugustAllWhitney #WhitneyBirthdayWeekend #WhitneyWeekend #Thankyou4teachingme XO."
Rihanna also paid tribute to the late singer by stepping out wearing a Whitney Houston graphic T-shirt on Saturday. Whitney's image was printed on the white T-shirt the singer was wearing while having dinner at Gjelina restaurant in Venice, California.
Whitney passed away at the age of 48 at a Beverly Hills hotel. The Grammy winner was found drowning in a bath hours before she was due to attend Clive Davis' pre-grammy party. Cocaine was found in her system. The hugely successful singer had long struggled with substance abuse.
Following the death of the singer, family members were concerned that Whitney's struggling daughter was also heading toward a life of addiction. Rumors circulated that Bobbi was going for a rehab.
