As friends rally to support her, Paris Hilton
can rest assured that her visiting hours in jail will be well-attended.
"We had a little party at her house the other night so we were all around her to be there for her," childhood friend Caroline D'Amore told PEOPLE at Wednesday's Los Angeles opening of the flagship Diesel store on Melrose Place.
D'Amore added that, at the Memorial Day barbecue
hosted by pal Nicole Richie
, "We all watched the first episode of the new season of The Simple Life,
which was really cute."
Still, another Hilton pal says the heiress is dreading jail time
. "She breaks down crying a lot because she just can't deal with the reality and pressure of everything that is happening," the source told PEOPLE, adding that some friends have not been so supportive: "She really can't take how most people around her have scattered and distanced themselves."
Hilton has until June 5 to turn herself in to the Century Regional Detention Facility in Lynwood, Calif., where she will serve a at least 23 days
for violating probation by driving with a suspended license.
Still, D'Amore said Hilton "has high hopes" for the future. Added pal Kim Kardashian: "[Paris] is a smart girl and will be okay. It's all about learning from her experiences."
