Back In The Swing Of Things

Just like old times!

Lindsay Lohan has returned to her partying ways. Sources reveal to PerezHilton.com that the recently rehabbed actress was in Vegas this weekend.

On Saturday night, she arrived at Pure….at 1:00 AM! And, she didn’t leave until several hours later.

Pure is the spot where Lohan was supposed to have her mega 21st birthday bash, but – instead – she opted for a beach party near her treatment facility in Malibu.

Now that she’s of age, though, she’s legally welcome in Vegas and making the most of it.

How long do you bet until she ends up back in rehab???
