Lindsay Lohan unfortunately left French Polynesia with more than a tan last month. The actress was briefly in the hospital in London this week, reportedly in connection with the pernicious virus she contracted while on vacation. But by Wednesday afternoon, Lohan was out and doing more of the community service that has occupied much of her free time since she’s been in England and performing onstage in Speed-the-Plow. Sure enough, Lohan tweeted today while with a member of CSV Positive Futures, the youth-volunteer nonprofit that the Mean Girls star has been affiliated with in London.
