Yesterday marked Lindsay Lohan's first day on the set of Labor Pains, her first paying film role since the abominable "stripper with dueling personas" fiasco that was I Know Who Killed Me. And while we can't imagine that the prospect of actually working (not to mention faking on-screen love with male co-stars) was leaving Lohan with anything other than a frowny face, somebody on the set had a really good idea as to how to motivate her. As these pictures show, it took only three things to cheer the seemingly sober-these-days star up to levels not previously seen since the Mean Girls days — too bad each of the vices things in question (including the delivery woman) aren't exactly good for her health.

After some time spent apart since their overseas girl-on-girl liplock heard 'round the world, hot item of the season Lindsay Lohan and Samantha Ronson finally reunited on the sunny Montreal Woodland Hills set of the fake-pregnancy caper. And though Lohan certainly looked relieved to see her favourite live-in girlfriend, her expression quickly turned south towards Ronson's goodie-packed hand. A hand bearing gifts like Red Bull (uppers!), Marlboro Reds (every healing junkie's favourite drug!) and some belly-tickling fingers Ronson used to remind Lohan just how much she loves the female touch.
