Kristen Bell's relationship almost stopped her fiancé landing a movie role.

The actress - who has been dating Dax Shepard since 2007 - admits producers on 'When In Rome' were initially concerned that casting the couple opposite one another could lead to problems on set.

She said: "When they started casting they knew Dax and I were dating and almost didn't hire him for that reason. I said, 'I get it, you don't want drama, but we're not very dramatic. If you want the best person, hire him!' "

The 29-year-old actress was thrilled when Dax was eventually cast.

She added: "They did and it was wonderful."

Kristen and Dax got engaged in January, but are in no rush to set a date for their wedding.

She added: "At this point who really cares? I don't know when it's going to be. People ask, 'When are you going to do it?' and I'm like, 'Wait, isn't this supposed to be the important thing? Getting engaged?' "
