The National Enquirer and Star Magazine claim to have the real reason behind K-Fed’s refusal to let Britney into his house shortly before she went to rehab. They say his ex and the mother of his two other children, Shar Jackson, was at his house helping him care for Britney’s two infant boys. They say that Shar wants K-Fed back, and if Britney found out she’s watching her children she’ll freak out as she’s still jealous of her.

What’s more, they claim K-Fed is telling Britney he’ll reconcile with her once she successfully completes rehab, and that’s what convinced her to give it a third try.

The Enquirer story also says that if Britney doesn’t finish rehab and sober up properly her family plans to commit her to a mental hospital.

The Enquirer has learned that while Britney is in Promises, her hubby Kevin Federline’s ex-lover, actress Shar Jackson, has been helping take care of their boys!

Britney is unaware of that fact, and people close to her don’t want her to find out because they are already concerned about her staying in rehab.

“Britney doesn’t think she has a problem. She agrees to go into rehab only because Kevin promised they’d be back together with their babies if she finished the program,” revealed a source close to the couple.

“Kevin has convinced Britney that he still loves her. He’s talked about all the things they’ll do when she gets out.

“But if Britney doesn’t stay in Promises, her family will put her in a mental health facility…”

“Shar has been at Kevin’s house helping him with the boys… Britney is terrified Kevin will get back with Shar. If Britney finds out what’s going on, she’ll go ballistic. There’s no doubt she’ll bolt from Promises and go running to get the kids.”

The article claims that Britney threatened to leave rehab if K-Fed and the kids didn’t visit her, and that’s why they were seen there last weekend. K-Fed has supposedly promised Britney that they’ll renew their wedding vows if she is successful at rehab.

I’m not sure I buy all that about Britney’s family wanting to commit her to a mental hospital, but it could be true that Shar is helping with the children. Maybe a paparazzo saw her leave K-Fed’s house when the kids were there. Star magazine says that Shar is trying to win Kevin’s affection and that she even cooked him his favorite meal, pasta and a dessert of carrot cake, for Valentine’s day.

There have been several stories lately about Britney and K-Fed getting back together. While I would like to think that they’re made up, there seems to be some truth to them. I wouldn’t put it past K-Fed to be sleeping with his ex Shar and getting her to watch the kids while promising Britney that he’ll reunite with her if she completes rehab.

Meanwhile Brooke Shields has offered Britney her help after hearing that she is reading her book about postpartum depression, “Down Came the Rain.” She said “If [Britney] is reading my book, I hope it’s helping her. If it’s not, and she wants to talk to someone, I’m available.”
