Whitney Houston and Bobby Brown had dinner together on Tuesday night – but that doesn't mean the former husband and wife are getting back together.
Patrons at Joe's Crab Shack in Alpharetta, Ga., were surprised when Brown and Houston – who divorced in April – showed up together.
Sitting at a table near the window and dressed casually, the couple – whose photograph was obtained by TMZ.com
– appeared to be engaged in pleasant conversation during their seafood and salad dinners. They even posed together for pictures with autograph seekers.
"They did eat here," the restaurant's general manager, David Evans, confirms to PEOPLE, "and they seemed to enjoy their meal."
Houston's publicist, Nancy Seltzer, tells PEOPLE that the singer and her ex-husband were in Georgia together. "They were there with their daughter," she said.
Although in May
Brown, 38, sued Houston, 44, for spousal support, child support and shared custody
, a source close to the two says that the former couple have remained close. In February, they also shared a dinner
, for the sake of daughter Bobbi Kristina, 14.
"They're still on good terms," says a relative of Brown's. "They don't hate each other."
Just don't expect a reconciliation anytime soon.
"No," said Seltzer. "They're friends, and they share a daughter. They're divorced."
"[Getting back together] is the furthest thing from their mind," adds the family member. "That's just not in the cards. They've got a history together, so they've got a lot to talk about. It's as simple as that."
