Uncle Joe is making her life a living hell.
Friends say Caroline ÂBiden is a âhot messâ with a history of booze and pill addiction â and she blames it all on the tremendous pressure she faces being the vice presidentâs niece.
âShe would complain about it all the time,â a confidant, socialite Paul Johnson Calderon, said without a hint of sarcasm.
âSheâs surrounded by a lot of people who use her because of who she is. Guys would want to date her because of who her Âuncle is.â
Cops were called to Carolineâs luxury rental apartment in Tribeca Tuesday morning when the 26-year-old allegedly went on a Âviolent rampage, screaming and pounding on the doors in a fight with her roommate over unpaid rent. Caroline was arrested for taking a swing at a Âfemale cop.
The Georgetown University grad resisted going into a holding cell at a precinct station house and was transported to Beth Israel Hospital in a rolling chair â bizarrely with a towel covering her head.
But Calderon said he wasnât surprised by her wacky antics.
âThe pressure of being Joe Bidenâs niece made her totally unravel,â he said. âItâs a desire for attention, a cry for help. Sheâs a very complicated girl who has a lot of feelings and a lot of issues.â
Carolineâs father, James Biden Sr., is the financier brother of the vice president. Family members have now grown so sick of her Âerratic behavior they have cut her off financially â sending her off the deep end, Calderon said.
âHer family has turned their back on her. Sheâs been abandoned by the family because they think that sheâs nuts.â
Calderon, speaking from a sober-living facility, said he ended their friendship because he felt that he couldnât associate with her while dealing with his own alcohol addiction.
âSheâs a hot mess,â he said. âSheâs like the Amanda Bynes, and Iâm the Lindsay Lohan â but in recovery.â
Caroline, who works at the Higher Pictures gallery on the Upper East Side, was known to disappear for weeks and once squatted at an apartment where she didnât pay rent.
She went to rehab while at Georgetown for alcohol and Adderall addiction, another friend said.
The university confirmed that she graduated with her bachelorâs degree in 2012.
Carolineâs dad paid the security deposit in August 2013 for her luxury pad that she subletted from NYU student Anne Marie Yacopetti.
Yacopettiâs mother, Marjie, claimed Caroline said she would pay the outstanding rent âwhen she feels like it.â
âItâs unfortunate that [Anne Marie] had to pay Carolineâs rent,â Marjie griped.
âWeâre just little white-collar people here,â she said, adding that her daughter moved back to California to save money. âIf youâre an elitist Biden, I guess you think youâre owed the world.â
Carolineâs other brush with the law came in 2009, when she was briefly detained by Amtrak police after a dispute over a train fare.
She felt that she was treated unfairly because of her last name and intended to pay the ticket on the train, a friend said.
The vice presidentâs staff did not return a call or Âe-mail for comment.
âThey donât wish to make any comment,â said a person answering the phone from the Biden familyâs home in Pennsylvania.
Caroline isnât the only wild child in the Biden family.
The vice presidentâs daughter Ashley, 32, was arrested for pot possession in 1999 and a âfriendâ tried to hawk a video of her snorting cocaine at a house party in 2009.
