Rolf Harris is to be retried on three sex offence charges and face one new count.
Last week a jury found the 86-year-old Australian not guilty of three assaults, following a trial at London's Southwark Crown Court.
The disgraced veteran entertainer, wearing a dark suit, white shirt and dark tie, appeared via video-link for Wednesday's hearing.
The former TV star is accused of four indecent assaults against three female teenagers, spanning two decades.
He will be retried for the alleged indecent assault of a 14-year-old girl in 1971, a 13-year-old girl in 1983, and a teenage girl in 1978.
He faces a new count of assault against the same complainant in relation to the 1978 allegation.
The retrial date is set for May 15.
Judge Alistair McCreath remanded Harris in custody, to which the defendant replied: "Thank you."
A spokesman for the Crown Prosecution Service said they had decided to seek a retrial "after careful consideration" following the jury being discharged last week.
"This decision was taken after consideration of all the matters set out in our legal guidance on seeking re-trials when a jury has failed to agree on a verdict," he said.
"The Crown Prosecution Service reminds all concerned that criminal proceedings against Rolf Harris remain active and that he has a right to a fair trial. It is extremely important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings.
