Bobbi Kristina Brown and Bobby Brown had some father-daughter time in the Big Apple on Tuesday -- and the late Whitney Houston's daughter and ex-husband didn't exactly pick a low-profile spot for their reunion.

A witness tells Us Weekly exclusively that Bobbi Kristina, 19, and her R&B singer dad, 43, had lunch at Blue Fin, located in the heart of Times Square.

The somewhat estranged twomsome were joined by Brown's longtime girlfriend, Alicia Etheridge and three other unidentified pals.

The group's Blue Fin lunch lasted about an hour and a half and, according to the witness, Bobbi Kristina "was on her phone and texting a crazy amount. She didn't seem too thrilled to be there, in all honesty."

Bobbi Kristina -- who briefly checked into the hospital following her mother's shocking Feb. 11 death at age 48 -- has kept a fairly low profile in the past month.

Appearing calm in a March interview with Oprah Winfrey, she said "I'm doing as good as I possibly can at this point. I'm just trying to keep going. . . I feel [my mom] pass through me all the time. I wake up at night."

She raised eyebrows later that month, when she stepped out holding hands with and kissing Nick Gordon, whom Houston informally adopted when he was just 12 year old. A source told Us the pair have been "living like a couple" in Atlanta.

"Bobbi Kristina is still so vulnerable since her mother passed away," the source added. "But Nick has become like her rock."

Her dad, Bobby Brown, meanwhile, was charged with a DUI in late March and faces up to six months in jail if convicted. He famously broke down in tears performing in concert hours after his ex-wife's death shocked the world.
