Nick Gordon calls Bobbi Kristina Brown his "best friend" and admits he is "lost without her" in his first Twitter post since her death nearly five weeks ago.

"I miss bobbi Kristina so much it hurts she was my everything in life and my best friend I love her so much and I'm lost without her," Gordon wrote in a post on his Twitter timeline on Monday. He later added, "I want her back and whiteny too I love u both so much r.i.p."

The only daughter born to Whitney Houston and Bobby Brown died under hospice care on July 26, after being rushed to a hospital emergency room after being found face down in the bathtub of the home she shared with Gordon.

The conservator of Bobbi Kristina's estate Bedelia C. Hargrove has since slapped him with a multimillion wrongful suit alleging that he gave her a "toxic cocktail" on the night of the incident. Over the six months she was hospitalized and under medical supervision family members also refused to allow him to visit her and he was not allowed to attend services for her.

The 25-year-old Gordon recently journeyed to his girlfriend's grave-site at the Fairview Cemetery in New Jersey, where he tearfully kneeled over and hugged her tombstone. Later, the New York Post reported Gordon was offered $40,000 for the photos by an unnamed publication and the funds were believed to have been steered toward his legal fees.

In the suit, Hargrove also alleges that Gordon regularly abused his girlfriend physically and stole from her during the time they were together.

Meanwhile, attorneys for Gordon have branded all the allegations put forth in the suit as "baseless" and slanderous against their client. Reps for Gordon also added rumors that he was paid for any Bobbi Kristina grave-site photos are "completely fabricated."
