7. Macaulay Culkin and Mila Kunis
In 2002, when Mila Kunis was 18 and Macaulay Culkin was 21, they bonded over their mutual love for the infamous animated show Family Guy. At the time, Mila was a voice actor for the adult animation, and Culkin was a huge fan of the show. The two got together and stayed together for 8 years! The split was a mutual decision as they both felt their lives were going their separate ways.
