LOS ANGELES — Britney Spears will temporarily lose custody of her two toddler sons to ex-husband Kevin Federline, sources told FOXNews.com ahead of the official ruling expected later Monday.

Commissioner Scott Gordon will order the boys, 2-year-old Sean Preston and 1-year-old Jayden James, turned over to Federline based on information that Los Angeles Family Court received over the weekend about Spears, the sources told FOXNews.com.

During Monday's custody hearing, Spears' former bodyguard accused the pop star of having "issues of nudity and drug use" since she returned from rehab, and reports of a planned "hit" on Federline emerged.

The bodyguard's attorney, the high-profile Los Angeles lawyer Gloria Allred, said in a press conference Monday that Spears' attorney chose not to cross-examine the bodyguard, who has been described as a "secret witness" against Spears in her custody battle with Federline.

The bodyguard, Tony Barretto, filed a declaration in the custody battle which alleges "nudity, drug use and safety issues post-rehab."

Allred said Barretto was prepared to testify under oath Monday, but neither the court nor Spears' attorneys chose to cross-examine him. She said his declaration went "unrefuted and unchallenged."

Barretto started working for Spears when she got out of rehab, and was fired on May 17 because, Allred said, "He did not hear her when he was asked to pick up her hat."

Barretto, himself the father of young children, came forward because while working for Spears, he became "very concerned" about the safety of her two boys, according to Allred.

Federline's lawyer, Mark Vincent Kaplan, said he was in court Monday because of a declaration that had been filed by him and because he wanted to be available should his client be cross-examined.

The ruling giving Federline temporary custody of his and Spears' children was expected to be handed down in Los Angeles Family Court later Monday afternoon.

Meanwhile, "Entertainment Tonight" reported that the FBI and the LAPD are investigating legitimate leads on a contract hit on Federline's life.

Multiple sources told "ET" that the FBI made attempts to contact Federline to inform him of the potential danger. The FBI reportedly told "ET" that the bureau could not confirm or deny an investigation.

TMZ.com said reports of an FBI investigation into a plot to kill Federline are completely untrue — but an LAPD investigation was conducted in the past.

According to LAPD, the department opened an investigation into a threat on Federline's life nearly two months ago, but the case was closed due to insufficient evidence.

TMZ also spoke with the L.A. spokesperson for the FBI, who blasted reports claiming that the FBI ever confirmed anything about a K-Fed investigation.

"The information on the Internet on these reports is not accurate. It did not come from the FBI at all," TMZ quoted the spokesperson as saying.

Spears married Federline in October 2004. She filed for divorce last November; it became official on July 30.

The two have had joint custody of sons Sean Preston, who turned 2 on Friday, and Jayden James, who turned 1 on Wednesday. Federline reportedly has been fighting to gain full custody of the two boys.

Kaplan said the custody battle would go on at least until the end of the year, and that two court dates were set, one in November and one in December.

He also said Federline is not seeking to modify his current monetary awards.

"All of these frenzied reports that he’s seeking custody related to money — they sound interesting but they’re not accurate," he said.

Spears gave a disastrous performance last week in her opening act at the MTV Video Music Awards, which was followed by more purported photos of her without underwear hitting the Internet.

She has an album due in stores on Nov. 13.

............I really hope things get better for Brit.

You know what? I feel sad for her. She's so obviously sick and needs some sort of help.

Hopefully those kids will be in a home that'll care for them.

this is for the best. I hate to say it but Kevin looks like a model citizen next to her and I think the kids are better off with him bc she's too much of a mess. I cant beleive she has freefalled so much. She needs help fast

Goodness, one would think Britney would have shaped up for her kids... I guess she'll have to hit rock bottom, before she sees what she's doing to them.

I agree. Instead of doing a freakin new CD she should take care of her kids first. I feel no sympathy for her.

She's already hit rock bottom, I don't know how much further she can go...

Hopefully, this will be the much needed wake-up call for her. If this doesn't do the trick, I don't know what will. It's obvious that she's ignorant to any mental, physical, and psychological problems she has. She also needs to get rid of those enablers in her life.

Britney, get better soon, please!

I'm not even going to comment on this.

Bash away at her people. You know who you are, and you know that you are going to.

She obviously needs help. Her children come first and foremost and right now, Kevin is the best thing for them. She does need to concentrate on becoming a better parent than being a better performer. How many wake up calls does she need? I don't feel sorry for her, I feel sorry for her kids. They need her yes, but they need a healthy mother. And a father and grandparents. I may seem harsh, but there are so many people out there that would die to have children and they are willing and able to care for them. Hey Britney, children need love, not money. Become a better parent, not a better singer

Great post Tishy! I totally agree!

I don't think any of us are bashing her. If anything, about everyone in this thread expressed concern for Britney and her situation. No one can deny the girl has problems, I think I speak for us all when I say I sincerely hope she can pull it together for the sake of her children, her own life, and her fans.

Oh I have no qualms about speaking my mind when it comes to this situtation. I don't care if the mother is Britney Spears, Julia Roberts, my next door neighbor or one of my relatives, I would still say the same thing about the mother. And in return, if a father had custody most of the time, I would also feel the same way. My BF and mine best friend is a man who has won custody of five kids because the mother is an unfit parent.

Clearly, from what has been published in legal documents (which is all that really counts) and her multiple trips to rehab, Britney doesn't deserve custody of her children until she is well. After she is better, her case should be reexamined by the state and if she is deemed fit, then she should have custody of her children.

Her children are the most important issue here. No ifs, ands or buts.

Exactly! And who knows what damage it has done to the kids now. It's a shame!

Great post I agree totally.

I hope she gets the help she needs. This is for the best right now and, hopefully, this can be a wake up call for her to get healthy so she can return to her children and be what they need.
