It's a day of Lohans here at Celebrity Milkshake, and it just keeps getting better and better. After talking about how Lindsay's dad is a whiny girl, we learn that, apparently, she is too! - only, replace "whiny" with "horny" and replace "girl" with "Jessica Alba husband stealer" and you got one hell of an apt comparison going.

There were barely any celebrities at West Hollywood hotspot Villa the night of November 19 -- which might be why Lindsay Lohan and Cash Warren immediately gravitated towards one another.

Film producer Warren, 30, was partying without Jessica Alba, his wife of one and half years and mom to his daughter Honor, 18 months. "When he goes out with friends, he gets into trouble," a pal says of Alba's husband in the new issue of Us Weekly.

Indeed. Soon after discovering one another at Villa, Warren and Lohan "ignored friends and just chatted." The real trouble began half an hour in. "Lindsay and Cash started making out," an onlooker tells Us.

"Lip on tongue," the eyewitness continues, "It was raw. They were not shy!"

Another Villa patron that night gasped, "It was a shock to see the two of them kiss, but it was real."

For her part, Lohan tells Us that the account is "absurd. He is married. I wouldn't dare kiss him."

But pals of both Lohan and Warren -- who share a love of nightlife -- insist otherwise. Those close to Warren and Alba worry that their marriage is already on shaky footing. "Jessica is not as into Cash as she used to be," one source says.

And the ever-fragile Lohan "becomes easily attached to everyone she meets and gets close to," one friend says. Adds another: "she's falling for [Cash]."

Lindsay's a whore! Jessica can't keep a man! No one cares who Cash Warren is! *GASP* ... Ok, look, there's really nothing new here. The only reason I'm posting this story is that it's a preview of the upcoming Lindsay-Jessica cat-fight. Papparzzi, you best have your cameras rolling on both at all times. I will be very angry if you miss a second when it goes down any time now. Hot damn, this is exiting.
