The Danish beauty was rumoured to have been stepping out with Ledger - who ended his engagement to Michelle Williams earlier this month (Sep07) - after they were spotted together at several events.
However, Christensen, 38, is tired of being constantly romantically linked with actors.
She says, "It is so annoying. I can't even tell you. The funny thing is that they write, 'Just out of a relationship with Josh Hartnett and now with Heath'. Josh is one of my dearest friends. ... And in several different tabloids they wrote that we were biting each other's faces off or something like that."
