Whitney and Bobby feasted royally during their Palm Beach vacation.

WILD Whitney Houston let her hair down and partied the night away with her bad-boy hubby Bobby Brown in Florida. The singer/actress has come under fire lately from friends who say her constant partying has gotten out of control.

STAR was there as Whitney and Bobby behaved like two newlyweds at Donald Trump's ultra-exclusive Mar-a-Lago club in Palm Beach, Fla.

"Whitney was knocking back mixed drinks," says a source.

"They were really lovey-dovey. Bobby was holding Whitney's hand and he kept kissing her neck.

Earlier in the week, the couple dined at Palm Beach's posh Charley's Crab restaurant two nights in a row. "They had a big appetite," says a source. "They ate enough for three people, then came back the next night for more!"
