In this clip, a growing number of grooms are getting involved in the once bridezilla-only wedding planning process. 'Good Morning America' correspondent Andrea Canning takes a look at the rise of groomzilla. "It was once like pulling teeth to get a groom-to-be to be part of the wedding planning," Canning explains as footage from famous wedding movies rolls. According to Canning, today's bridezillas are finding their territory being "invaded by an unexpected partner in crime: the groomzilla." In an interview, a wedding planner says that 75 percent of her brides now bring the groom to coordinate.

"But why the sudden uptick? Partially because more grooms these days are paying for the wedding and simply want more input," Canning reports. "For some, experts suspect it's men embracing their feminine side." Footage shows one couple shopping as the bride complains, "He can be loud and say, 'This guy's too expensive! We're leaving!'"
