Lindsay Lohan is Now Having Sex with Adrian Grenier

Lindsay Lohan has returned to America.

And she's brought her sexual appetite from Italy with her.

Having left Alessandro Di Nunzio, Dario Faiella and many others behind overseas, the Firecrotch Queen is now working it in the States. First stop?

The bedroom of Entourage star Adrian Grenier.

"They're talking," a source close to the pair told Perez Hilton, hinting that a great deal of penetration is involved in these supposed talks.

Sources also state that Lindsay and Adrian went out on a romantic date to the Polo Lounge at the Beverly Hills Hotel on Wednesday night.

"No paparazzi," said the insider of the secret meeting. "Since they're relationship is new, they wanna keep things as private as possible."
