Is Lindsay Really Trying to Stay Sober?

Rehab-hopping Lindsay Lohan threw herself back into the hornet's nest over the weekend -- by popping into the Hollywood bar scene.

TMZ spies didn't see her drink, but she tempted fate by keeping company with premiere party pal, Paris Hilton.

The tabloid twosome created a paparazzi firestorm Friday night as they laughed and joked on their way out of Les Deux nightclub. Then, less than 24 hours later, TMZ cameras caught Lohan sneaking out of Area nightclub -- alone.
