Saturday, Aug. 9 marked what would have been the late Whitney Houston's 51st birthday, and no one wanted to honor the special occasion more than the pop icon's daughter Bobbi Kristina. 

"#HappyBirthdaymommy ! #HappyBirthdayWhitney ! #AllAugustAllWhitney #iloveyou ! @nickdgordon @mwhitaker10 #Family," she tweeted along with a photo of a small cake. 

Kristina took her mother's February 2012 death hard, tattooing the diva's initials onto her wrists. 

In addition to the birthday cake, it looks like Kristina wants to continue honoring her mother throughout the month. 

"GoodmorningAll ! Having a wonderful #AllAugustAllWhitney #WhitneyBirthdayWeekend ! I love you my lady :) #WhitneyWeekend @nickdgordon," she tweeted on Aug. 10.
