Nick Gordon released a statement about girlfriend Bobbi Kristina's condition on Friday, and over the weekend, he added another heartfelt remark about the 21-year-old starlet via Twitter. Gordon changed his profile picture to a photo of his Bobbi Kristina tattoo, and he tweeted on Sunday, "Thank you for all your prayers. She is a strong person and will pull through this. Continue to pray for her."

Bobbi Kristina was found face down in her bathtub two weeks ago, and she's remained on life support since being placed under a medically induced coma just one day after the accident. There were reports that Bobbi Kristina's organs were shutting down, but a number of her family members have stated that her condition is in fact improving, so it's not clear what's really going on.

New reports have surfaced about her emotional state prior to the accident, alleging that the aspiring singer was abusing the prescription drug Xanax. Bobbi's former boyfriend Zach Jafarzedeh just spoke with The Daily Mail and revealed that Bobbi used to take the anti-anxiety medication every morning and that she used it far more often than she was prescribed. Jafarzedeh added that Bobbi Kristina had been very upset after a number of disagreements with Gordon over the last few months.

"I know they got into a fight a few days before and she was really depressed about that and probably took a few Xanax and bathed and fell asleep," he said. "Some of it makes me feel like it could be a possible suicide, not even just a mistake. Something symbolic like, 'This is the way my mom died, this is the way I want to kill myself too.' It's eerie how similar that is. It sent chills down my spine and it made me sick to my stomach when I heard about it."

On her drug use:
    "She did more drugs before her mom died. She was more messed up then. She saw what happened to her mom and wanted to learn from that. She smoked cigarettes but she didn't like to smoke marijuana. She didn't like the way it made her feel. Cocaine was a very small phase of her life, she didn't do it often. The main things she would do were drinking, Xanax and cigarettes."

On her relationship with Gordon, Jafarzedeh added, "Everybody's trying to make it all, 'Nick Gordon beat her up' but I don't believe that. I don't believe he beat her up and threw her in the bathtub. That's kind of stupid, why would you put her in a bath if her mom just died in a bathtub?"

Still, Jafarzedeh doesn't speak very highly of Gordon, noting that the two fought regularly and that Gordon had a penchant for buying guns and fast cars:
    "Nick was getting a little wild. He was getting into car accidents. He's been in about three or four accidents over the last couple of years. He's got a need for speed. He was trying to get away from Bobbi and starting fights. I know that Nick could be aggressive. I know he got into fights in high school. But I never saw them fight physically ... He pulled a gun on me. He didn't directly face it at me, but he came out with the gun. I wasn't scared, Nick and I were too close back in the day, and he wasn't pointing it at me. I had heard he had just recently bought the gun, so he was trying to flash it, show it off."
