Lindsay Lohan LLohanDogMidnight031809_014.jpg

Last night, X17 photogs outside of Lindsay's (er, Sam's) house report that they heard screaming and crying, and they began to prepare for yet another round of drama. However, shortly after the ruckus, we snapped Lindsay and Sam leaving the house with Sam's adorable bulldog Cadillac, and the girls were all smiles! Had they already kissed and made up, or were they just putting on an act for the cameras?

The couple packed their overnight bags, hopped into Sam's black Porsche, and headed to the Chateau Marmont, where they spent the night. We have no idea why the girls would stay at the lux hotel instead of their own pad, but maybe Cadillac has the answers?

Calls to Cadillac's rep were not immediately returned.
