Anna Nicole - Killed by Caffeine?

Could caffeine have helped kill Anna Nicole Smith? One theory being floated this morning says that Anna drank so much soda, which interacted with her Cipro, causing severe insomnia, which then led her to overdose on chloral hydrate, her eventual downfall.

The theory is posited by FOX News, and their "expert source" says that taking Cipro and drinking soda at the same time (several soda cans were found around her bed) kept Anna Nicole awake and unable to sleep, which she tried to counteract with choral hydrate, the powerful but dangerous sedative. Broward County toxicologist Howard Schueler acknowledged that both caffeine and Cipro were in her blood, but didn't confirm that their combined effect would be overly strong.

Schueler did say, as Dr. Joshua Perper said Monday, that the Ativan, Valium, Klonopin, and the chloral hydrate together were a lethal mix for the late Anna Nicole.

Diddy Diddles for Hours

Immodest rap mogul P. Diddy wants the world to know that he really can go all night long – and all day, and almost all night again. Diddy is claiming in a London tab that he and his baby-mama Kim Porter had tantric sex for "at least 30 hours" on their recent trip to Paris. "As meticulous as I am with my work, I'm more meticulous with lovemaking. I like to do it for a long time," says Puffy.

Meanwhile, as fulfilling as his sex life might be, Diddy tells People that he's going through "Snoop withdrawal," missing his partner-in-rap, Snoop Dogg, after the Doggfather was denied entrance to Britain during their current tour. The two will be reunited in Dublin, not to worry.

Lindsay Shills for Condo, Didn't Buy Anything

So did you hear that Lindsay Lohan bought this swank new condo in Midtown Manhattan? TMZ certainly did. Turns out -- oops -- that the developers of the Atelier building on West 42nd Street are just letting La Lohan use the apartment – in exchange for her star power in promoting the project, according to Page Six. Lohan is neither buying nor renting the place, says a source, but is going to look for her own crib sometime later this year. And Lindsay isn't the first celeb to trade a pad at the Atelier for some PR love – tennis star James Blake and model Maggie Rizer have also lent their names to the building's marketing materials.
