15. Mila Kunis and Ashton Kutcher

Although their gap is not significantly huge, it is worth mentioning because Mila Kunis (41) was only 14 when she met Ashton Kutcher (46) on That '70s Show. While Ashton, five years her senior, was playing her on-screen boyfriend, probably unaware that their onscreen chemistry would transition to a marriage. They reconnected years later, proving that timing is everything. With two kids, hilarious Cheetos commercials, and a love story straight out of Hollywood, these two are simply adorable.
