Despite reports of fighting in recent weeks, Lindsay Lohan and her girlfriend, DJ Samantha Ronson, enjoyed a nice night out at LA hotspot Genghis Cohen restaurant on February 24. Instead of hiding behind the turntables, she took the stage for an acoustic performance with guitar-playing and singing, leaving the shy Sam anxious before the show. “Lindsay assured her that she’d be fine,” an onlooker noted, adding that Sam smoked several cigarettes with her gal pal and ordered a Jack Daniel’s cocktail to calm her nerves. With her gal pal on stage, Lindsay snapped pictures and constantly asked if Sam needed anything, according to the onlooker. Pregnant pal Nicole Richie and Paris Hilton’s ex Stavros Niarchos were also there to cheer her on. “Everyone was extremely proud of her and told her she was great,” the witness adds.
