Now this is a Mr. Big deal.

Lauren Hitt, the former communications director for Mayor Kenney, is now chief spokeswoman for Sex and the City star Cynthia Nixon's campaign for governor of New York.

Hitt's new position was first reported by the New York Daily News, which noted that she previously served as communications director for "Philadelphia Mayor Jim Kennedy," a mistake Politico also picked up.

It's unclear when Hitt joined Nixon's campaign. In her Twitter bio, Hitt lists herself as Nixon's chief spokeswoman, but it appears she only began tweeting about Nixon's campaign Monday.

The University of Pennsylvania graduate and Baltimore County native who may best be known around Philly for reigning in Kenney's Twitter rants, left his administration in January.

She went on to work for the campaign of Randy Bryce, a Democrat and Army veteran who is running for retiring House Speaker Paul Ryan's seat in Wisconsin's First Congressional District.

Nixon, who played attorney Miranda Hobbes on HBO's Sex and the City, announced her candidacy for governor in March. She will face Democratic Gov. Andrew Cuomo in New York's September primary.
