Nicki Gordon has visited the grave of his late girlfriend Bobbi Kristina Brown, three weeks after the 22-year-old daughter of Bobby Brown and Whitney Houston was laid to rest. People magazine reports that the grieving 25-year-old was finally able to pay his respects on 17 August when 'some generous friends' flew him to New Jersey to visit her grave.

Bobbi Kristina died on 26 July at Atlanta's Peachtree Christian Hospice, almost six months after she was found unconscious at her home. She was buried next to her mother at Fairview Cemetery in Westfield, New Jersey, on 3 August.

Gordon's visit comes weeks after he vowed to hold his own memorial service after being allegedly banned from her burial ceremony. In a message posted on Facebook, the 25 year-old revealed that he wanted an intimate service attended by those that were "there for her".

"We will have our own service remembering and honouring Krissi. Only the real family that actually was there for her will attend," he wrote under a post regarding Bobbi Kristina by close friend Mason Whitaker.

Meanwhile, Gordon's legal woes continue to rumble on after the aspiring actress' court-appointed conservator Bedelia Hargrove filed a civil lawsuit blaming her husband Gordon for her 'wrongful death' and alleging he stole thousands from her bank account.

Legal documents stated on 17 August that he murdered the reality star by giving her a "toxic cocktail" of drugs before putting her face-down in the bathtub at their Georgia home.

Gordon, who was 12 years old when Houston took him in after his father went to prison and his mother was unable to take care of him, strongly denies the allegations and no criminal charges have been brought against him.

"The recent lawsuit against Nick is slanderous and meritless. Nick has been heartbroken and destroyed over the loss of his love and it's shameful that such baseless allegations have been presented publicly," Gordon's legal team of Joe Habachy and Jose Baez said.
