The 36-year-old, who has just separated from Arab prince Jafar, arrived at his exclusive Belgravia property at 3:30am to pick up some of her belongings.
And, when he refused to let her in, Campbell allegedly began shouting so loud she woke up his neighbors, who called police.
Cops arrested Campbell for breach of the peace, before driving her to a nearby road and she was later freed once she had calmed down. They then returned to Jafar's house to collect her belongings.
Last weekend, Campbell made the headlines when she reportedly caused $54,000 worth of damage to Jafar's yacht following an argument with an Italian chef.
She is also currently fighting three lawsuits, all filed by former employees who claim the supermodel assaulted them.
Los Angeles police suspect Haley Joel Osment was under the influence of alcohol when he crashed his car in the early hours of Thursday morning.
The 18-year-old suffered a broken rib, fractured right shoulder blade, cuts and abrasions when he crashed his 1995 Saturn station wagon into a pillar and flipped it at 2:10am (PST) in the community of La Canada-Flintridge.
'The Sixth Sense' star was not charged by police, but L.A. County Sheriff's sergeant Mark Slater admits "we suspect alcohol played a role in the accident."
Osment - who was driving alone - was not able to take a breathalyzer test at the scene, but a blood sample was taken after he was admitted to Huntingdon Memorial Hospital in Pasadena, California.
Slater tells the New York Daily News, "The results will not be ready for another three weeks. There is going to be a full investigation."
