Heath Ledger and Michelle Williams have vowed to let the world know when they finally marry, by flashing their wedding rings at photographers. The pair, parents to one year old daughter MATILDA, are furiously protective of their privacy and refuse to respond to rumours about their impending nuptials. But Ledger insists they'll make a subtle announcement when the time is right. The Australian star says, "We try not to talk about it, to keep it our own kind of thing. It's obviously very sacred. People write stories regardless. The stories haven't necessarily been bad. So we're letting people run with their assumptions." When asked what announcement the couple will make, Ledger replies, "Photos of us wearing our wedding rings."
