A new post on Whitney Houston's website, written by her sister-in-law Patricia Houston, notified fans that it was Bobbi Kristina's birthday.
"Today is Bobbi Kristina's 22nd birthday and we ask you to continue to keep her in your prayers as she is still fighting the battle of her life."
Today is also Bobbi Kristina's 33rd day on life support, since she was found unresponsive in her bathtub on January 31, according to PEOPLE.
Nick Gordon, Bobbi Kristina's boyfriend, also tweeted for her birthday.
