The "Oz the Great and Powerful" star says she started dodging questions about their relationship even more and more, reported Us magazine.
"I censor myself. Lately, more. More. I've always said that it is much easier to be honest than to be caught up in a bunch of lies. At least this way, you know who you are," the 29-year-old said.
The actress, who ended her eight-year relationship with Macaulay Culkin in 2010, also said she is ready for a career change.
