Whitney died of accidental drowning on Feb. 11, 2012 at age 48. She was found unconscious in a bathtub at the Beverly Hilton Hotel. Bobbi Kristina died on July 26 while in hospice care. However, her death came just months after she too was found unresponsive in a bathtub in her Georgia home.
Bobbi Kristina's boyfriend, Nick Gordon, discovered her in the bathtub and in an interview with Dr. Phil, his mother Michelle claimed Nick tried to administer CPR to Whitney after also finding her in the tub. "When Whitney was found, he administered CPR to her and called me as he was standing in front of her saying, 'Mom, why couldn't I do it? I couldn't get air into her lungs,'" she said about her son's alleged traumatic experience.
The Coroner Investigator on Whitney's case later disputed this claim to ET, saying, "As far as I know, the bodyguard and the personal assistant pulled Whitney out of the bathtub, but they did not perform CPR."
Both Whitney and her ex, Bobby Brown, publicly struggled with addiction during their tumultuous relationship. Shortly after Whitney's death, cocaine and heart disease were ruled to be contributors.
During an interview with Oprah Winfrey in September 2009, Whitney admitted to using drugs with her former husband, saying he "laced marijuana with rock cocaine."
Bobbi Kristina also faced speculation that she too had issues with substance abuse.
In July 2014, a photo appeared on Instagram that showed someone who supposedly looked like Bobbi Kristina inhaling smoke from what appeared to be a bong. "I've never posted any photo of me doing anything!" she tweeted in response to the image. "This is someone trying to tarnish and make a horrible name for MYSELF. People are insane."
In June, ET spoke with Ian Halperin, the author of the unauthorized biography, Whitney & Bobbi Kristina: The Deadly Price of Fame, who claimed that drugs were a part of Bobbi Kristina and Nick's lifestyle.
"I have incontrovertible evidence the last few months they were together, they were on drugs almost all the time," he alleged. "It's just proportion to heights nobody could even imagine. And drugs were prevalent in their lives. ... They got completely out of hand and it was a ticking time bomb."
Whitney and Bobby's marriage came under even more scrutiny when the Bravo show, Being Bobby Brown, aired in early 2004. The show seemed to offer an almost too real look at the couple and was only on the air for one season.
In June, Bobbi Kristina's court-appointed conservator filed a lawsuit accusing Nick of controlling Bobbi Kristina by limiting who she could interact with. The lawsuit also claims that Nick often answered her cell phone, would not allow her to make appointments without his approval, and manipulated her bank relationship so that he could access her money.
Bobbi Kristina also had music and acting aspirations like her mother. She spent some time in the recording studio, and while she didn't get as far with music as her mother, she did inherit her fierce commitment and loyalty to her family.
"I'm most excited for people to see our family together as a unit just working together being an actual family," Bobbi Kristina told ET in 2012 regarding the reality show The Houstons: On Our Own. "It's not anything that's fake -- nothing like that. It's us being a family and us getting through it together, and that's how it is."
On Monday, Bobbi Kristina's family said goodbye to Whitney's only child, much in the same manner as they did when the music legend died over three years ago.
Like Whitney's funeral, Bobbi Kristina's casket was also transported in a gold hearse to the Whigham Funeral Home in Westfield, New Jersey. From there, she was laid to rest at Fairview Cemetery alongside her mother.
As they did at the time of Whitney's heartbreaking burial, fans also gathered at the cemetery to pay tribute to Bobbi Kristina. Some onlookers even held photos of the music icon with her daughter.
Another similarity between these two services was that family friend Tyler Perry transported both Whitney and Bobbi Kristina's bodies in his private jet to New Jersey. An ET source says the filmmaker was thanked profusely on the program at Bobbi Kristina's memorial service, which was held on Saturday in Alpharetta, Georgia.
"She brings me a lot of joy," Whitney told ET in a 1993 interview. "She brings both Bobby and I a lot of joy. It's a different thing when you become a mother. It changes your whole perspective on life. You really don't live for you anymore. You're living for your children."
