With her Golden Globe-nominated role as Natalie Portman’s foil in Black Swan, actress Mila Kunis is on the cusp of A-list status. Whether or not her bigger star contributed to her breakup with longtime boyfriend Macaulay Culkin, however, remains to be seen. Kunis’ rep confirmed on Monday that she and the 30-year-old Home Alone star separated after seven years together. “The split was amicable, and they remain close friends," her rep told Page Six. A source claims that the couple actually broke up some time ago, but were keeping the split under wraps while Kunis promoted Black Swan. The 27-year-old actress, best known for parts in That 70’s Show and Forgetting Sarah Marshall, will next be seen on the big screen opposite Justin Timberlake and Emma Stone in the romantic comedy Friends With Benefits in July.
