Keira Knightley: bridezilla? Not so much, the bride-to-be revealed on the Ellen DeGeneres Show Thursday.

The "Anna Karenina" actress, who is engaged to Klaxons keyboardist James Righton, told DeGeneres that she finds weddings "kind of quite confusing."

"I'm just not one of those girls that's had that fantasy wedding thing," Knightley said. "I really haven't planned anything and it's all quite terrifying."

Knightley said she's turned to the Internet for help, but doesn't understand wedding traditions like "bridal tea parties."

"I don't get what the big deal is," she said. "You say, 'I do, 'I do.' You drink a bit. Isn't that it?"

Knightley and Righton reportedly met through mutual friend and fashion expert Alexa Chung, and got engaged in May after more than a year of dating.
