Bobbi Kristina Brown heavy PDA with Nick Gordon at Romeo’s New York Pizza

Even though they have denied their romance, Bobbi Kristina Brown and Nick Gordon definitely are still getting hot and heavy, they can’t deny the passion.

New pictures and video show Whitney Houston’s daughter Bobbi Kristina, 19, engaged in heavy PDA with her pseudo-adopted brother Nick Gordon, 22.

Bobbi Kristina was seen in a full-on lip-lock with Nick Gordon during a lunch run in Atlanta on Tuesday, confirming suspicions the two are romantically involved.

Nicholas Gordon has denied a relationship with Bobbi Kristina Brown, but the pair was just spotted making out and canoodling again in Atlanta.

Bobbi Kristina Brown and Nick Gordon were seen showing some heavy PDA in Atlanta on March 13, TMZ reports.

According to HollywoodLife.com, Bobbi Kristina Brown and Nick Gordon were spotted at Romeo’s New York Pizza in John’s Creek, Georgia.

Their lunch date was super-romantic, according to a source inside the restaurant, who also confirmed that they frequent the pizza place and are often seen around town.

“A few of my friends went to school with Bobbi and they definitely know her around here,” the source said.

“They were here Tuesday and Monday and they’re in here a lot.”

Furthermore, the source said that they do not hide their PDA at all.

“They’re always all over each other,” the source said.

“They don’t try to hide it at all. I’m surprised they’re saying that they’re not together.”

Whitney Houston unofficially “adopted” Nick Gordon into the family roughly 10 years ago after learning he was having problems at home. He’s been living with the Houstons ever since.
