Lindsay Lohan Back To Tweeting, Staying Out Late

Lindsay Lohan is back on Twitter for the first time since she surrendered herself to jail on July 20.

"Clearly.. Paparazzi shouldn't be allowed to take pictures or video while someone's driving or at a stop light. 4every1's sake #trafficpolice," she tweeted on Thursday.

Here is Lindsay in her first post-rehab photo, with headphones and an energy drink Wednesday morning. She may have been paid to have the drink on hand for the photograph.

She also went to the DMV to get her license reinstated on Wednesday then hit the town in a rented Maserati that night, Red Bull in hand and picking up friends at 12:30 am, People reports.

Lindsay's friends are worried her recovery won't last.

"Lindsay says she's determined to stay sober and focus on work," a source told People. "[But] it's too soon to tell what will happen. We've seen these moments of 'purity' before, but as soon as she gets a taste of the nightlife and the drama, she usually falls back into old habits fast."

And as Us Weekly speculates, she's also back fake tanning.
