This is why Justin Timberlake and Cameron Diaz broke up

Although there could be innumerate reasons why Justin Timberlake and Cameron Diaz parted ways, one could be that they felt the same about marriage at the time. Namely, the former boy band star didn't seem to be in any rush to walk down the aisle, either, and he wasn't afraid to say so with a few eyebrow-raising comments in a very public forum.

Appearing on The Ellen DeGeneres Show in 2006, the titular host asked (via TMZ), "I need to know ... Should I get a bridesmaid dress now or not?" Timberlake responded with, "Go ahead, reserve one ... The only thing is, you will have to stay the same size for the next 15 years." That same year, the pop star reaffirmed his ideas about marriage and children during an interview with British GQ. "Men are monkeys, man," he said. "Listen, as for marriage and so on ... I have my two dogs for kids so you should ask them how I'm doing!" The publication noted that Timberlake's girlfriend at the time, Diaz, was within earshot, and he appeared to try to correct his answer with, "Never say never, but why ruin a good thing?" 

But it would seem that the damage had already been done — it doesn't exactly make sense for a couple to stay together when neither appear to be in it for the long haul.
