Though it was reported that Paris Hilton and Britney Spears were BFFs by about half the entertainment websites out there, the other half are reporting that Britney is threatening to release a lesbian sex video tape of Paris and one of her friends – unless Paris becomes a nicer person. While we reported that Paris gave Britney some career advice at her birthday party this past weekend, according to several other sources, the two didn’t rekindle their friendship at all, but instead had another falling out.

Britney Spears has threatened to release video footage of one-time friend Paris Hilton in a lesbian romp with a mutual pal, according to reports. Brit has demanded that the heiress stop being rude to her and members of her entourage. The troubled star has reportedly threatened to leak the footage, which shows Hilton in a compromising position with another woman, unless her attitude changes.

A source said: “The letter warns Paris that if she continues being rude to people, the footage will be leaked online.” Australian newspaper The Sydney Daily Telegraph reports the former friends fell out at Spears’ 26th birthday parties in Hollywood last weekend. But a source close to Hilton said: “It’s obvious Britney and her bratty pals are being silly. Paris laughed when she got the letter and said it was c**p.”

So they’re either best friends again, or total enemies. Take your pick. It definitely doesn’t seem like Brit shunned Paris on her birthday – there are tons of photos of the two together, and they look happy and normal (in that fake, plastic way they both do). This article is all over the internet. Most everyone is sourcing The Sun, whose article sources the Sydney Daily Telegraph, whose article sources The Daily Mail. Strangely when I search the Daily Mail’s website, I can’t find any mention of Paris and Britney in the same article that’s more recent than the end of November – and the party in question took place this past weekend. So just in case you were all stressed and worried and freaking out about the possibility of a Paris Hilton lesbian sex tape, I think this might just be one of those unsubstantiated internet rumors. But then again I thought that about “One Night in Paris” too.

Picture note by Jaybird: Here’s Britney Spears, wearing a pink wig and drinking what appears to be a mimosa, (along with some cigarettes) with her Realtor at the Four Seasons hotel on Wednesday. My mom is a Realtor, so I have it on good authority that they do insist their clients wear neon acrylic wigs whenever they take them to look at homes valued over $2 million. And it’s totally normal to get your clients drunk afterwards. Image thanks to WENN. Header of Paris hosting the Wednesdays Party at Mansion Nightclub in South Beach last night.
