Britney cleaned up well and dressed modestly for a party at Vision nightclub in Atlanta to promote her husband Kevin Federline’s new critically-panned rap-like album last night.

Britney and Kevin have a shaky relationship as everyone knows, and it’s nice that Britney is trying to support Kevin, however misguided his career.

Britney and her mother are said to be fighting. Britney was supposedly “in shock” after her mother refused to fly out to Hawaii to lend her support after Britney and Kevin had a row. Mrs. Spears may be annoyed that Britney is quick to ask for help but slow to act on everyone’s advice that she leave Kevin.

Update: The party was a belated birthday party for Kevin, according to Wireimage. We added four more pictures of Britney and Kevin that are less flattering. Three more after the jump.
