While Bobbi Kristina Brown fights for her life at Emory University Hospital in Atlanta, rumors abound regarding the truth about her relationship with "husband" Nick Gordon. Days after the 21-year-old entertainer was found unresponsive in the bathtub of her Atlanta home, her father, singer Bobby Brown, is speaking out about his daughter's romance with Gordon, 25.

Despite Brown and Gordon referring to one another as husband and wife, Bobby Brown's lawyer confirmed to People Magazine Tuesday that the singer's daughter was never legally wed. "Bobbi Kristina is not and has never been married to Nick Gordon," Brown's attorney said in a statement. While it is being alleged that Brown never officially married Gordon, the couple does have a long history together.

After years of friendship, the duo stated their romance in 2012, following the death of Brown's mother, singer Whitney Houston. Prior to her passing, the pair lived together in Houston’s abode. Gordon, who called the award-winning songstress “mom,” claimed that Houston allowed him to move in with her at the age of 12 because he was going through a difficult period in his life. Despite reports that Houston had adopted Gordon and that Brown was legally his sister, the couple stated that there was no truth to the rumors.

“My mom never adopted him,” Brown confirmed to Extra in January 2014.

“We were young. Krissy looked at me as an older brother, and I looked at her as a little sister.... [Whitney] just treated me like she gave birth to me. She treated me like a son. Excuse me for saying this, but treated me better than my birth mother. I owe everything to her,” Gordon said.

Despite receiving flack for their relationship, the duo announced their engagement in October 2012. In January 2014, they announced that they were married. “It put a fire in us,” Brown told Extra of the backlash and their decision to announce their allegedly unofficial union. “It lit a fire up under our a--, and we went haulin',” Gordon said. “The critics can say whatever they want to say. It’s like we have a force field and that s--- [is] just bouncing off of it.”

But the negativity about their relationship didn't only come from the general public. Days after Brown's near-drowning, several publications reported that Brown's family was not a fan of Gordon. “Krissy’s family would like to have Nick out of the picture,” a source told Radar Online. According to the webloid, Gordon has been barred from visiting Brown while she is receiving medical treatment.

While it is being alleged that Brown's family isn't a fan of Gordon, he told Extra in January 2014 that Houston was a huge supporter of their romance. “[Whitney] made me promise several times to look after Krissy. I will never, ever, ever break that promise," Gordon said.

Brown and Gordon were last photographed together near their shared home in Roswell, Georgia, in January. Their outing followed the release of Lifetime’s controversial biopic about Houston's personal life and career. In photos published by the Daily Mail, Brown, in an effort to shield herself from photographers, can be seen wearing a leopard print blanket.

The couple is best known for co-starring on the now defunct reality series "The Houstons: On Our Own," which debuted in May 2012 on Lifetime. The series also starred several other members of the Houston family.
