The Sex and the City star married her fiancee Christine Marinoni in May (12), not long after she shaved her head to play a cancer patient in Broadway play Wit.
Nixon has now revealed her dramatic new look caused tensions as she prepared for her big day.
She tells America's Elle magazine, "I'd shaved my head to play a professor with ovarian cancer in Wit and my hair had just started to grow back. My wife was worried that my being bald was all anybody would want to talk about. My mother kept making suggestions like, 'Look at this cunning beaded cap Whitney Houston wore to her wedding, isn't it great?'"
The actress turned to her wedding dress designer, Herve Pierre, creative director at Carolina Herrera, for help.
She adds, "I considered wearing a veil but luckily Herve Pierre came up with something better, just a little bit of silver and white ribbon wrapped twice around my head, to which we affixed some small Fred Leighton diamond love birds.
"It made me feel like Tatiana from A Midsummer Night's Dream and you want to have that kind of magical feel on your wedding day."
