Lindsay Lohan just had a huge day in court … but now, she wants us to believe she's changed her ways! Lohan says that it wasn't her featured in photos that some outlets did in fact claim were of the 26-year-old troublemaker hiding under a jacket (in a car emblazoned with the logo for Mr. Pink energy drink, which she promotes) as she attempted to get into a Hollywood nightclub the same day as being in court (on Monday). "Guys relax, that was NOT me at A/V," Lohan wrote on Tuesday in a series of three tweets. "I'm taking this seriously and focused on the road ahead. I stayed in last night, after a pretty long day...and ordered sushi to my hotel. Don't believe EVERY little thing you hear, unless you hear it from me. The support I have gotten, has been great and means alot." Also on Tuesday, Lohan was working hard to pay off that $50,000 debt to Mr. Pink after the company chartered her a private jet after she missed not one, not two, but three commercial flights from New York City to Los Angeles for the start of her trial. The actress, who is now back in the Big Apple, posted a photo on Instagram of her standing in a bathroom mirror holding a can of Mr. Pink's ginseng drink. Lohan has until May 2 to check into "lock down" rehab. It has been reported that she may report to a facility in NYC, where she has been living since the end of 2012.
