Celebrity wedding planner Colin Cowie stopped by HuffPost Live on Wednesday to discuss modern wedding etiquette. The planner had some strong words for "bridezillas" (like this one) who mistreat their friends and family.

"I do not believe in any bad behavior at all, whether you're getting married or not getting married," Cowie said.

Cowie, who has planned parties for Jennifer Aniston, Tom Cruise, Jennifer Lopez, Oprah Winfrey and Kim Kardashian, urges brides to remember, "It's really not about impressing your guests, but making them feel welcome and comfortable." Ensuring they're comfortable starts with treating them right.

For more of Colin's advice and information about his new wedding guidebook, watch the full clip from HuffPost Live above.
