Kate Upton: 'I hate planning my wedding, but I love shopping for gowns'

Model-turned-actress Kate Upton is struggling to plan her upcoming wedding to baseball star Justin Verlander - and still hasn't set a date.

The couple has been engaged since early last year (16) and Kate can't wait to become Mrs. Verlander - but she's having problems nailing down a date between her husband-to-be's Detroit Tigers schedule and her own busy acting agenda.

"I'm really excited about getting married," she tells news show Extra. "It's just the wedding planning sucks.

"It's gonna be a good date no matter what. As long as we're surrounded by friends and family."

And there is one part of the wedding prep she is enjoying - the hunt for a dress.

Kate was spotted gown shopping in Spain back in April (17), but she admits she still hasn't picked the perfect outfit for her big day.

"There are so many dresses and designers, it's been fun to look around," she adds. "I’m excited to finalize everything."

Upton, who is currently promoting The Layover, her new movie with Baywatch beauty Alexandra Daddario, has previously revealed some wedding day secrets, explaining she'd like to get away for her nuptials.

"(I'd like) a destination wedding," she said. "We don't really get the opportunity to go on a lot of vacations together because of how long the baseball season is, and how busy we both are, so I think that what we want for our wedding (is to) have all of our closest friends and families go on an extended vacation together."

And she also wants to test her fiance's allergies on their wedding day with a room full of blooms: "I want a lot of flowers," the busty Sports Illustrated Swimsuit model recently told Martha Stewart Weddings, "and I know I want the petals already down by the time my niece, who will be my flower girl, walks down the aisle.

"But Justin has terrible allergies. He'll have to take an allergy pill."
