Rebecca Javeleau, 14, mistakenly made the details public when inviting friends to the event, creating an internet sensation that led to thousands of RSVPs from strangers.
Her mother, Tracey Livesey, 40, cancelled the October 7 event, but police have been forced to step up patrols in the girl's street in Harpenden amid fears some Facebook users will turn up, causing chaos.
The girl, a pupil at Sir John Lawes School, had meant to invite only 15 friends to her 15th birthday party, but within hours of appearing online the event escalated out of control as her mistake was subjected to online ridicule.
At one stage, 21,000 Facebook users had clicked the RSVP button signalling they would attend the party, including fake celebrity accounts in the name of Justin Bieber, Professor Stephen Hawking, Stevie Wonder, Susan Boyle and Rick Astley.
Miss Livesey said: "Her party is cancelled and she will be lucky to get a birthday card from me after this. I said she could have 15 friends along to the party but my sister-in-law said that 8,000 people had said on Facebook that they were coming.
"She did not realise that she was creating a public event and should have done. She is going to have to change her mobile phone SIM card because of the number of calls she has been getting about it. In February, a family's home was "trashed" after their teenage daughter advertised a party on Facebook, which was gatecrashed by dozens of adults.
Rachel Ross, 15, "advertised" a small party for friends on Facebook but more than 50 people arrived and caused havoc at the home in Merseyside.
Furniture was smashed, drunk revellers urinated on children's beds and some ceremonial swords used for decoration were ripped down and embedded in a wall. The damage was estimated at around £15,000.
In 2008, an Australian teenager who hosted a party attended by 500 guests was arrested by police who were alerted by furious neighbours in a suburb of Melbourne.
