1. Mila Kunis & Ashton Kutcher
How long they’ve been dating: The former That ‘70s Show cast mates took their friendship to the next level in April of 2012. In recent months, their romance has taken them everywhere from Australia to Italy to New York to Iowa, where they dined with Kutcher's family at Red Lobster (if that's not love, then we don't know what is). Kunis even planned a surprise birthday party for her guy this year at Go Kart World in California.
An insider tells People that the “Sexiest Woman in the World” (as voted by FHM magazine), 30, and her 35-year-old actor/producer beau are vocal about wanting to have kids together: “I can’t imagine it will be very long before she’s pregnant. [Maybe] right after they get engaged if not sooner,” the source predicted.
