To pass the time in rehab, Lindsay Lohan enjoyed wandering around the Promises treatment center nude, with the intent of titillating the staff at the clinic. A little birdie present at Allegra Versace’s birthday party eavesdropped on a conversation in which Lindsay was boasting about her birthday suit misadventures. From the National Enquirer:

“Lindsay was howling with laughter as she told all her friends, including Bruce Willis’ daughter Rumer. They were all giggling too and their eyes were popping out.

“Lindsay said, ‘I drove them all mad wandering around completely naked. They kept telling me to quit, but it was so much fun to tease all those boys. I just couldn’t stop it!’.”

Maybe she was still in stripper mode after filming, “I Know Who Killed Me.” However, it seems that these naked flirtations still weren’t enough to hold the attention of Lindsay’s on-again, off-again boyfriend, Calum Best. With Lindsay very publicly trying to take this attempt at sobriety seriously, Best is finding that this new Lindsay just isn’t the party girl who initially stole his heart. A source dished to the Daily Star:

“Calum called Lindsay on Friday (20Jul07) and said that he was finding her post-rehab existence dull and that he didn’t want to give up partying.

“Calum loves Lindsay, but he’s simply not in the same place as her anymore.”

He could be heard lamenting, “Ugh. It’s like she’s ALWAYS in rehab. Or naked. Or naked in rehab. BO-ORING.”
