Now that baseball season is over, New York Yankees star Nick Swisher and Joanna Garcia are deep in wedding planning mode, but Swisher insists no one is getting out of control.
“I don’t understand,” the athlete tells PEOPLE. “Why would you get all upset about one of the greatest days you could have in your life? Jo’s done such a tremendous job; she asks me for my opinion [and] I give it to her.”
“If she doesn’t pick what I like,” he says, “I’m cool with that.”
Garcia, 31, star of ABC’s Better with You, announced her engagement to Swisher, 29, last May. Swisher is currently “team captain” of the Art of Shaving team for the Money for Movember campaign, which seeks to raise money for cancer research.
