Paris Hilton made sure to have several stars witness her special day.

On Thursday, the hotel heiress married entrepreneur Carter Reum. Her parents, Kathy and Rick, as well as her wedding guests, were photographed arriving at the venue – her late grandfather’s $60 million Bel Air estate, ahead of the ceremony.

Paula Abdul, Emma Roberts, Bebe Rexha, and aunt Kyle Richards of "Real Housewives" fame were among the star-studded guest list. Hilton’s longtime pal, Kim Kardashian, was also in attendance, TMZ reported.
