Houston and Brown reunite for Grammy night

Whitney Houston and estranged husband Bobby Brown were spotted dining out together in Los Angeles on Sunday night, prompting reports the pair are giving their marriage a second chance.

Houston, who was in town to attend music mogul Clive Davis' pre-Grammy Awards party on Saturday, skipped the prizegiving ceremony to enjoy a quiet meal at celebrity-friendly restaurant Dan Tana's in West Hollywood with Brown and their daughter Bobbi Christina.

Last week, Houston asked the authorities overseeing her divorce to fast-track proceedings. She initially filed for divorce in October.

The 43-year-old is working on her comeback album after battling with a drug problem.
