Britney Spears is planning to marry her personal assistant in Las Vegas, it has been claimed.
The 'Gimme More' singer - whose 2004 Vegas wedding to childhood friend Jason Alexander was annulled after 55 hours - is reportedly infatuated with assistant Sam Lufti and has already told ex-husband Kevin Federline and her lawyers she is planning to tie the knot.
A source said: "Britney is completely under Sam's spell. Everyone sees through him, except her. I hear that he stays with her most of the time, and she pays for his food, his bar and restaurant tabs and his clothing. She takes care of everything.
"Her lawyers have begged her to at least get a prenup, but she didn't seem to be listening."
Kevin, 29, is said to be furious about the 26-year-old singer's plans as he does not want Sam to be stepfather to his sons, two-year-old Sean Preston and 15-month-old Jayden James.
A family insider told America's Star magazine: "Kevin has seen Sam lose his temper. We hear he swears a lot and makes very derogatory statements when he's alone with Brit.
"Kevin has forbidden Britney from having Sam around the boys. In fact, Kevin has threatened to get a restraining order. She'll lose custody if she allows Sam around them, Kevin will make sure of it."
Meanwhile, Kevin's lawyer Mark Vincent Kaplan will appear in court today
(18.12.07) to discuss Britney's night of partying last week, on the same day she claimed to be too ill to attend her court-ordered deposition.
Inside sources say Kaplan plans to ask the judge to prevent Britney getting more custody of the boys until she sits for her court-documented questioning with Kevin's legal team. He could also request Britney's lawyers be blocked from depositioning anyone on Kevin's side.
Kevin currently has temporary full custody of the boys and receives £15,000-a-month in child support from Britney, while she has three supervised visits a week.
They have agreed to share custody over the Christmas holidays, but Kaplan may even appeal for Britney's current visitation rights to be withdrawn. |
