Like a true party girl, Sand arrived at 12:30 am at Syndicate Hospitality's latest Hollywood hotspot MyStudio. Sands joined some girlfriends and stayed until closing time. Sources close to Sand tell Breaking Celebrity News it appeared she was having a very good time, and had a table by the dance floor and was seen dancing the night away. Sand left the club at 2:30 a.m. and was greeted by VH1 cameras.
