A 49-year-old man is in police custody after allegedly attempting to enter actor Jamie Foxx’s hotel penthouse March 31 in Philadelphia, where the actor was filming Law Abiding Citizen. According to reports, William Brown first tried to make contact with Foxx after knocking on his door, claiming to be Beyonce’s producer. Though Foxx shoved the man out of his room, Brown returned March 31, when police were called. Brown, who was charged with stalking, is being held on $250,000 bail and will appear in court April 7.
