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.
