London, Dec 3 (ANI): It seems that Paris Hilton's relationship with Britney Spears may be more than just a platonic friendship. The hotel heiress had raised eyebrows when pictures of her in a lesbian clinch with Venezuelan MTV star Eglantina Zing during a modelling shoot started making the rounds. However, though Hilton herself has insisted that the two "were just larking around", an inside source revealed that she and Zing had definitely got hot and heavy, and that Hilton was now having a bit of a problem keeping her hands of Spears. "Paris just couldn't keep her hands off Eglantina. And she responded-kissing and running her hands all over Paris's body. But right now Britney's the one - Paris can't get enough of HER!" the News of the World quoted the source, as saying. And it seems that's what really has the princess of pop's family worried, for Britney has been increasingly losing her clothes (read underwear) in Hilton's company. "Paris loves the fact that Britney gets turned on by going commando. She even demanded that Britney take her knickers off in front of her. Britney just obeyed," the source revealed. The insider also let slip that it had been spontaneous combustion for both women the moment they met in Las Vegas two weeks ago. "They went into a toilet and came out 20 minutes later, clothes and hair all over the place. They love to prance naked in front of each other and that night they really got to know each other," the source said. The insider revealed that Britney's mum Lynne is now seething, for she believes that Britney's antics will come back to bite her, and that the 'Toxic' singer might even end up losing custody of her sons to estranged hubby Kevin Federline. "She (Lynne) was relieved when her daughter dumped rap husband Kevin Federline. But with Britney going for custody of her two young sons, Lynne fears her antics might influence the judge," the source said. (ANI)
