Rachel Uchitel - best known as Tiger Woods' mistress #1 - is checking into Celebrity Rehab, RadarOnline.com has learned.

Uchitel, 35, will appear on the fourth season of VH1's Celebrity Rehab with Dr. Drew. Uchitel, a New York party planner, will be treated for an addiction to pills, according to the New York Post who cited a network source.

The paper says the source did not specify what kind of pills Uchitel has an addiction to, although, as RadarOnline.com has previously reported, Uchitel was known to have taken the sleeping pill Ambien with Tiger while they had sex.

Jeremy London has been ordered to complete 20 anger management classes after pleading guilty to a misdemeanor charge of getting into a fight with his estranged wife.

The Party of Five star had originally been charged with spousal battery but that was knocked down and a pending trial averted with the deal reclassifying the argument London and his wife Melissa had last November over their five-year-old son in Palm Springs.

Jeremy London's domestic battery case went to trial on Tuesday and RadarOnline.com has exclusively learned the District Attorney plans to put his 5-year-old son Lyrik on the stand to testify.

Jeremy, 39, was charged with domestic battery for an incident with his estranged wife, Melissa Cunningham, late last year after she told Palm Springs, Calif. authorities that an argument over the custody of their child escalated to violent proportions — an allegation Jeremy has adamantly denied.

Jeremy London was recently charged with domestic battery for an incident with his estranged wife last year, but RadarOnline.com exclusively spoke with the actor who said he's trusting the courts will learn the truth — that he was falsely accused.

"There are women who are legitimately abused in this country, and it is so important that the system is set up to protect them. If I have to go through this process to ensure that the system works and can protect victims, then it's worth it," Jeremy told us in an exclusive interview.

"Many men are falsely accused and the system is usually able to discern fact from fiction... While it's troublesome I wouldn't have it any other way."

Jeremy London’s estranged wife accused him of violence during an argument over their son, and RadarOnline.com exclusively learned that Child Protective Services stepped in after the ordeal.

Jeremy has a four-year-old son, Lyrik, with Melissa Cunningham, but Melissa’s mother has had full adoptive custody of the boy for more than a year.

“CPS got really concerned when they heard about the allegations of violence and all the drama surrounding the whole incident,” an insider told RadarOnline.com.

The Palm Springs Police Department wants to speak with Jeremy London after his estranged wife, Melissa Cunningham, accused him of assaulting her, but RadarOnline.com has exclusively learned Melissa purposely “created the drama” for a reality TV show she’s trying to get on.

“Melissa has been recently contacted by a reality show wanting her to appear as a ‘celebrity ex-wife,’” a source close to the London family told RadarOnline.com.

“She left messages with several of her friends and family members last week saying that the show wanted her to create conflict and drama between herself and Jeremy, and specifically they wanted her to create a scenario that makes Jeremy look bad.”

Just because he's wanted by the Palm Springs Police doesn't mean Jeremy London doesn't have time to party in Hollywood.

As RadarOnline.com reported, the bad boy former Party of Five actor is wanted for questioning in Palm Springs after his ex-wife accused him of assaulting her during an argument over custody of their son.

But Saturday night, he was carrying on with his brother Jason and a bunch of friends at the Hollywood bar Cat and Fiddle.  It was a belated birthday party for Jeremy who turned 39 on November 7.

Sgt. Reed from the Palm Springs Police Department confirmed to RadarOnline that officials are still looking to speak to London and have still not heard from him.

"The police report has been completed and has been passed on to the Detective Bureau who will assess the case tomorrow and further investigate," Sgt Reed said. "This is standard procedure."

When told that London had been out partying in Hollywood last night, Sgt. Reed said that he "hadn't heard that information before" but that they were still very interested in speaking with the actor.

The Palm Springs Police Department wants to talk to an old friend, Jeremy London.

The former Party of Five star has been accused of assault. The accuser, RadarOnline.com has exclusively learned, is none other than his ex-wife Melissa Cunningham.

The cops have not released Cunningham's name, saying only that a London "girlfriend" contacted them, claimed an argument over the custody of their child became violent outside her Palm Springs home, and she had been injured.

London and Cunningham have a son, Lyrik, 4 who is in the custody of Melissa's mother.

"London has not yet surrendered himself to the police and we currently have patrol and detectives investigating the case further," Sgt. Reed from the Palm Springs PD tells RadarOnline.com exclusively.

"A warrant has not yet been issued for his arrest in the alleged assault but depending on what happens during the course of the investigation, then that may be an option. Under California law if a person assaults their spouse or the mother of their child then it is a felony.

"During the argument London had with the woman, she sustained minor visible injuries to her hand but refused emergency care."

As RadarOnline.com reported extensively last year, London and Cunningham had a tumultuous relationship with him telling us she is "a very sick person."

The comment followed London's bizarre episode where he was kidnapped by drug dealers, and forced to take drugs himself.  Few believed his story -- including Melissa -- but the tale was proven to be true when one of the men was arrested.

In a plea bargain, Brandon Adams pleaded guilty to auto theft and false imprisonment charges."

In the middle of it all, London appeared on Celebrity Rehab.

Despite Jeremy and Melissa's rocky history, his rep Dominic Frisen tells RadarOnline.com, ""This is a false allegation and we understand that the police have to follow protocol in issuing an arrest warrant -- standard when any woman files a complaint of domestic abuse. However, no such abuse occurred and these allegations will soon be proven false. We anticipate Jeremy to be cleared of any wrong-doing as he continues to enjoy fatherhood and embrace sobriety."

The rep also said that per the court agreement, "Jeremy has unsupervised continuous visitation with Lyrik" but Melissa is prohibited from being alone with him.

Following his guilty plea in an Indio, California court, actor Jeremy London’s accused kidnapper, Brandon Adams, was released from jail on Wednesday and London’s family couldn’t be happier, RadarOnline.com has exclusively learned.

"We are pleased that Brandon is going home after many months in jail. The DA obviously didn't feel there was credibility for a case and offered a deal that would get Brandon out of jail immediately,” the statement given exclusively to RadarOnline.com from Jeremy’s brother, Jason London, his fiancée Sofia Karsten and the boys’ mother Debbie Nielsen, reads.

“Otherwise, this case would have gone to trial and such lesser charges would never have been offered. Brandon pleaded to far lesser charges – NOT to what he was being accused of – so that this could be over and he could go home to his family.
