Max Clifford has been found guilty of indecently assaulting teenage girls over nearly 20 years.
Spin doctor Clifford, 71, faced 11 counts of indecent assault against seven teenagers.
He was convicted of eight charges, cleared of two and the jury was unable to reach a verdict on one other.
Clifford was convicted following a six-week trial that exposed the 'terrible, festering secret' that he was a paedophile who bullied and manipulated teenage girls into performing sex acts.
Clifford was granted conditional bail but told by the judge that that should not be taken as an indication of the sentence that would be passed on Friday.
Clifford, who made his career brokering lucrative deals between the tabloids and people who wanted to sell their stories, left Southwark Crown Court without speaking to the press. The man who tried to spin his own story from his arrest last April said: "I've been told by my lawyers to say nothing at all."
The guilty verdicts make Clifford the first suspect to be prosecuted successfully under Scotland Yard's Operation Yewtree investigation, which was sparked by the Jimmy Savile scandal in late 2012 and has led to a spate of arrests but – until Monday – not one conviction.
Jenny Hopkins, deputy chief crown prosecutor for CPS London, said: "Today's verdicts provide a long-denied justice to the victims of serious sexual offences. I would like to thank these victims for having had the courage to come forward and give evidence.
"The victims of sexual abuse, whenever it may have taken place, should know that police and prosecutors will listen.
"It is only right that we now take some time to consider our position on the hung count and we will update the court accordingly."
The jury was told that Clifford was a 'master in the art of intimidation and manipulation' who preyed on starstruck girls by promising to introduce them to the world of showbusiness in return for sexual favours.
The millionaire publicist, who has represented a string of stars in his five-decade career, used his New Bond Street office as his own 'sexual fiefdom' and impersonated Hollywood icons to lure girls into his grasp, the court was told.
He convinced one 18-year-old aspiring actor she could meet singer David Bowie if she performed a sex act. Another was said to have been promised a role in a James Bond film and he allegedly told a third he would secure her a role in Dynasty to repay her favours.
Summing up six weeks of evidence, Rosina Cottage QC, prosecuting, described Clifford as a risk-taker with an 'arrogant confidence', urging jurors to reject the defence's claim that he was a 'loving father' who had no interest in young girls.
Ms Cottage said: "He has managed to portray himself in different ways to different people, but don't be fooled.
"In every case his actions were sudden, unexpected and, frankly, in some cases so bizarre you may think these young women and girls have no idea how to react."
Witnesses described how he referred repeatedly to his 'tiny' penis and, at other times, put on fake accents in telephone calls to his victims.
