Her freedom didn’t last long.

Moments after she was sprung from court without bail, the busty Bronx serial bride was busted again — for fare beating, police sources said.

Liana Barrientos, 39, and her niece Tracy, 19, were caught trying to get a two-for-one deal on a subway ride at 149th Street and Grand Concourse around 2:40 p.m., sources said.

The women were trying to enter the subway station through an emergency exit door without paying, sources said.

They’re both charged with theft of services and criminal trespass.

Hours earlier, Liana Barrientos pleaded not guilty in Bronx Supreme Court to two counts of felony offering false instruments for filing in her 2010 marriage — her 10th nuptial in 11 years.
