Last week ,HollywoodLife.com reported that Bobbi Kristina Brown and Nick Gordon were holding hands and kissing on the lips while shopping at Target near their home in Johns Creek, Georgia.

“We’re just close,” Nicholas Gordon told ABC.

“Just going through her mom’s passing and grieving together.”

On March 9, Bobbi Kristina and Nick Gordon were also spotted walking around Target and kissing on the lips and holding hands, which clearly showed the two are more than just friends.

Nick Gordon is not blood related in any way to Bobbi Kristina Brown, but Whitney Houston took him in 10 years ago when his dad went to prison.

Bobbi Kristina and Nick Gordon have been living in Whitney Houston’s town home in Atlanta for years and they’ve even tweeted that they sleep in the same bed sometimes.

Plus, Nick Gordon’s grandmother told Star magazine that he is very close with Bobbi Kristina and took care of both her and Whitney Houston.

In a report put out by E! News, a source close to Bobbi Kristina Brown explained that Nick Gordon is a great person and friend and has always been supportive of the 19 year-old beauty.

The insider also dished that the pair first met when they were younger, when Nick Gordon explained to Bobbi Kristina that he wanted to enlist in the army after high school due to family problems – but, to avoid this from happening, Whitney Houston stepped in to take him in as her own son.

Since Whitney Houston fostered Nick Gordon, he has been the man of the house, and by the looks of his recent tweets, he feels the same way about this relationship.

Since the release of Bobbi Kristina and Nick Gordon photo together, there have been many controversial tweets and he is firing back, as he wrote: “All the haters that dont know us or th real story can’t un follow me. I don’t give a f**k.”

 He also added: “Some ppl have no lives so they gotta be in ours.”

Whitney Houston’s adopted son also made his place in the family known, stating: “She called me her <<God Son>> I swear some ppl in this world act like they don’t have a brain…”

Nick Gordon closed out his defensive remarks by writing: “I’ve proved my loyalty to her and the Houston family. I don’t owe any of you anything. Ha I don’t even know y’all haters.”
