“[Sam] told security to look out for Lindsay and block her from getting in,” a source told the magazine. “Lindsay, of course…booked a room at [the hotel] Chateau and fully intended to crash the party and make a scene.” The tipster added that the decision was made to prevent Lindsay from “causing a scene and ruining Charlotte’s night”.
