Did Mila Kunis‘ breakout role in “Black Swan” contribute to a breakup for the actress, who’s flirting with movie stardom? Kunis’ rep confirms that she and one-time child star Macaulay Culkin have gone their separate ways. “The split was amicable, and they remain close friends,” her rep said. Kunis started dating Culkin seven years ago, when she starred as the snobby “Jackie” character in “That ’70s Show.” A source said the couple split some time ago but has kept it low-key while Kunis promotes the movie.
