AceShowbiz - Olivia Culpo, the former Miss Universe, recently wed San Francisco 49ers running back Christian McCaffrey. In the lead-up to the ceremony, she enforced a strict guest policy that even her sister, Aurora Culpo, had to abide by.

Olivia Culpo did not invite her sister Aurora Culpo's new boyfriend, Paul Bernon, to her June 29 wedding. The reason, she explained on the July 3 episode of Aurora's "Barely Filtered" podcast, was that she had never met him.

"He's not invited to the wedding, if that's what you're asking," Olivia said. "If that's what you're going to say." Aurora, 35, called the remark "rude," but Olivia, 32, quickly retorted, "No, [it's] rude to invite somebody I've never met."

Aurora then tried a different approach, asking if her "friend" could attend. Olivia again declined, saying, "Yeah, okay...flavor of the month? Not interested."

Olivia clarified that it was not a reflection of Bernon's character but rather her sister's choice. "Sorry, it's not a reflection of you, it's a reflection of my sister," she said.

Aurora previously shared that she had been dating Bernon, the ex-fiance of "The Real Housewives of New York City" alum Bethenny Frankel, for about two months. A source told Us Weekly that they met online and have many mutual friends.

Although Bernon was not invited to the wedding, he did participate in some pre-wedding festivities, according to US Weekly. Aurora and Paul first sparked romance rumors in June.
