Bobbi Kristina celebrates mother Whitney Houston's birthday

Pop icon Whitney Houston's daughter Bobbi Kristina remembered her mother on her 51st birthday.

"#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 honouring her mother throughout the month.

"Good morning All ! Having a wonderful #AllAugustAllWhitney #WhitneyBirthdayWeekend ! I love you my lady. #WhitneyWeekend @nickdgordon," she tweeted.
