Is Jennifer Love Hewitt's break from Jamie Kennedy strategic?

It coincides with the release of her memoir/dating advice book The Day I Shot Cupid, subtitled Hello, My Name Is Jennifer Love Hewitt and I'm a Love-aholic, all of which is very Men in Trees, is it not? Or, maybe they split up long ago and she's going public now since she knows it'll come up during book tour. Either way, she wants you to know, "Some people get excited about being single. i don't."
