Keira Knightley superstitious about raising toast!

Los Angeles: Actress Keira Knightley is superstitious about raising a toast the right way. She believes if she wouldn`t stare hard at fiance James Righton when he popped a champagne cork on Valentine`s Day, they would end up with a `sex curse`.

She believes couples can be hit with seven years` sex curse if they avoid eye contact when clinking glasses for a toast, reports thesun.co.uk. "If we`re not looking into each other`s eyes when we toast, that means seven years` bad sex. Can`t have that," said Keira. IANS
