Reality star Nicole Richie and pop singer Christina Aguilera have given birth to babies born roughly an hour apart at the same Los Angeles hospital, reports said Saturday.

Richie, the daughter of soul singer Lionel Richie and rock star partner Joel Madden welcomed a baby girl at the Cedars Sinai Medical Center, according to People magazine's online edition.

Shortly on the same ward, Aguilera, who married music producer Jordan Bratman in 2005, gave birth to a baby boy, according to reports.

Richie Madden named their daughter Harlow Winter Kate Madden and have now left the hospital, a spokesman for the couple said.

Richie, a close friend of socialite Paris Hilton, whose partying has been the subject of intense tabloid speculation, said in an interview last year that pregnancy had forced her to grow up.

"When I found out that I was pregnant, there was just something inside of me that felt a responsibility to mend any issues that I've had with my parents in the past, because, listen, I've put them through a lot," she said.

An for Kevin Federline wants the Los Angeles Police Department to release its investigative report on an incident at ex-wife Britney Spears' home a week ago that led to the pop star losing custody of her two sons.

According to a court order released by Los Angeles County Superior Court on Friday, there was a hearing Thursday in the couple's child custody dispute. Federline's attorney, Mark Vincent Kaplan, asked for the police report and also requested the names of the law enforcement officers who responded to the situation.

A hearing on the requests was set for Monday.

Early month, police intervened when Spears refused to return the children to her ex-husband after a court-monitored visit. After a standoff, Spears was taken to a hospital in an ambulance that was chased by a crowd of photographers.

The next day, Commissioner Scott Gordon awarded sole legal and physical custody of the boys, one-year-old Jayden James and two-year-old Sean Preston, to Federline and suspended Spears' visitation rights.

Spears left Cedars-Sinai Medical Center a day and half later.

According to the court order, the judge denied a request from Spears' lawyers to close Thursday's hearing to the media.

Court Allan Parachini said it would be unusual if the attorneys did not move to close Monday's hearing to the media.

O.J. Simpson, famously acquitted of murder in the mid-1990s, was taken into custody on Friday after prosecutors asked a Las Vegas judge to revoke his bail for trying to contact a co-defendant in an armed robbery case.

Clark County District Attorney David Roger told a judge in court papers that Simpson, who is accused of leading an armed robbery of his own sports memorabilia from the Palace Station Hotel and Casino on Sept. 13, should be jailed for trying to dissuade the co-defendant from cooperating with authorities.

A court spokeswoman said the football star-turned-actor had been taken into custody in Florida, where he now lives, by his bail bondsman and was being brought to Las Vegas for a hearing into the matter.

If District Court Judge Jackie Glass finds that Simpson, 60, violated the conditions of his US$125,000 bail, he could be held in jail until the trial.

Roger in court papers that Simpson violated his bail terms by leaving a profanity-laced message for Stewart with the bondsman.

Simpson's attorney, Yale Galanter, could not immediately be reached for comment.
