Alli Sims is promoting her new single — available now on iTunes — and that means we can look forward to lots of not-so pleasant rehashings of Britney Spears’ 2008 emotional breakdown in the weeks to come.

Alli, who is the pop star’s cousin, claims she’s been warned to keep her distance from the singer. Jamie Spears has been in charge of the 27-year-old’s estate, finances and well-being since she was hospitalized in January 2008.

And Alli, 28, says he controls who has access to Britney.

“I was told that if I picked up the phone when she called or if I called back, then I’d have to deal with the lawyers. So I decided to back away, I really didn’t have a choice. I don’t have the funds to fight it,” says Alli, who once served as Britney’s personal assistant.

“I had to take myself out of the situation until she’s in control of her own life again. I feel bad for her because I’m sure she probably thinks that in a way I abandoned her,” the aspiring “singer” remarks sadly.

Alli adds, “Everybody wants to get something from her. It has got to the point where she doesn’t trust anybody, which breaks my heart.”

Alli Simms has dropped dime on to Us Weekly about Britney Spears’ fling with Adnan Ghalib. Perez Hilton claims Brit’s cousin and confidante dished for a $200,000 payday, brokered by ger aunt, Lynne Spears. Us, on the other hand, denies offer Alli any form of a payout. The tabloid claims the aspiring songstress is friends with one of their reporters and was compelled to speak out against the relationship out of concern for Britney.

“I do not think Adnan is a good person,” Sims, 26, tells Us. “I think he only has bad intentions. He has given me a weird feeling and creeped me out. I wish he would just go away.”

Sims is adamant that Spears was not on drugs before she was hospitalized on Jan. 3. “I do not think that is the issue at all,” she tells Us. “I was with her for eight months pretty much every day and never witnessed anything like that – and I lived there.”

Last week, we told you about Britney Spears appendage Alli Simms’ plans for an “Entourage-style reality show” set to hit the airwaves next Fall…well….there’s been a little bump in the road. With Britney gone half-crazy and Alli distancing herself from the kooky Spears clan, the show’s producers have lost interest and pulled the plug on the project.

“While Britney was being hospitalized in LA, Alli, her supposed best friend, was self-promoting in NYC. She was flown in for meetings to draw attention to her career — including her reality show. Only problem is, it’s not happening,” a Life & Style insider claims.

“While she was partying in New York at Tenjune, the Maloofs decided to drop the idea. Although it was supposed to be Alli’s show, Britney was always the main draw.”

“Alli and Britney are obviously not close anymore, and Alli’s even had a falling out with the Spears family. So the Maloofs (show producers) lost interest in going forward!”

Alli Simms has parlayed a reality show out of her role as Britney Spears’ cousin and sometimes assistant. The aspiring singer has teamed up with the owners of Las Vegas’ Palms Hotel, the Maloof Brothers, to shoot a reality show pilot that follows the mini-celebs and her friends.

“It’s going to be like a female version of Entourage, but for real,” a mole reveals to In Touch Weekly.

“[Alli] knows a lot of interesting people.”
