"Hey … they're probably just exchanging sobriety tips! Lindsay Lohan has been spending a lot of her newly free time with an old friend (and once rumored flame), hotelier Vikram Chatwal. The duo went on a shopping spree together around SoHo in New York City on Tuesday before having dinner with pals at ABC Kitchen. Wonder why Vikram's name sounds familiar? The 41-year-old was arrested in April after trying to get on a plane with a large stash of drugs (specifically, cocaine, marijuana and prescription pills). Chatwal was sentenced to 12 months of in-patient rehab, and it was reported he was at Silver Hill hospital in New Haven, Connecticut, earlier this month getting sober. Vikram — whose properties include the Dream Hotels — has been romantically linked to Lohan, although that has never been confirmed.

In September 2012, she was arrested for fleeing the scene of an accident after she grazed a pedestrian outside the Dream Hotel in NYC's Chelsea neighborhood. The following month, she and mother Dina reportedly partied there until 4 a.m. before getting into an altercation that resulted in police being called to the "Liz & Dick" star's childhood home in suburban New York after the 27-year-old and her mom became involved in a domestic dispute. Lindsay, who recently sat down with Oprah Winfrey after finishing her sixth stint in rehab, told the talk show host she is a changed woman. "The Canyons" actress has a sober coach in NYC and even canceled a trip to Europe when Oprah suggested it might not be the best thing for her sobriety. Let's just hope Lindsay's sobriety coach keeps her away from the Dream!"
