A Long Island teen is accused of drunkenly slamming her car into an elderly woman as she was driving home from a boozy sleepover, cops said Monday.

Christina Burns, 17, of Selden, left her friend’s house on Ashford Drive in Bohemia at 6:50 a.m. Sunday — still allegedly drunk off spiked seltzers, according to Suffolk County Police

On her way home, Burns struck a mailbox, drove across a lawn and hit 80-year-old Che Yeung, who was walking in the street, before driving away, cops said.

Police connected Burns to the crash after she rear-ended another car 30 minutes later at the intersection of Route 347 and Route 25 in Nesconset, according to police.

Yeung was brought to Southside Hospital in Bay Shore in critical condition. No injuries were reported in the second accident, according to cops.

Burns was arrested and charged with driving while intoxicated and leaving the scene of an accident with serious physical injury, according to authorities.

Francis Rogalle, 50, was charged with violating Suffolk County’s Social Host Law and faces a $500 fine for allegedly allowing underage drinking at her home.

Burns was scheduled to be arraigned at the First District Court in Central Islip Monday.
