A straphanger pleaded guilty today to slashing three people inside of a Queens train station after she got bumped the morning rush hour.

Dina Saint-Fleur, 25, admitted cutting Princess Allsop, Roody Antoine and Andres Nova with a knife inside of the Sutphin Blvd/Archer Avenue subway station on Sept 12.

Saint-Fleur told investigators she’d been targeting Allsop after getting bumped, and hadn’t meant to slash her other two victims.

In return for the guilty plea, Dina Saint-Fleur, 25, will be sentenced to two years behind by Queens Supreme Court Justice Dorothy Chin-Brandt in November.

She could have face up to seven years if she’d been convicted at trial.

She’s being held on $150,000 bond.
