Lindsay Lohan‘s Hollywood Hills home was broken into Sunday morning while the 23-year-old and her sister, Ali Lohan, were at a birthday party. This was the second time her home has been burglarized in the past three months. Lohan returned home at 3:00 a.m. and called her father Michael, who then called police. Lohan’s publicist, Leslie Sloane-Zelnik, said security surveillance video has been given to police to help in their investigation. During the burglary, a safe was ripped off the wall and jewelry, bags and shoes were stolen. Michael Lohan told TMZ that he believes the robbery was an inside job, because his daughter’s staff neglected to turn the alarm on.
