When Keira Knightley tied the knot last week with her new rocker husband James Righton, the nuptials themselves weren't the only aspect noticeable for their laid-back atmosphere - the bride's dress itself was remarkable for its effortless look. In fact, it appeared to be a dress the Oscar-nominated star had even publicly worn before.

But it seems our Keira wasn't the MOST unconventional celeb bride out there. This weekend saw US reality TV star Mama June (just close your eyes at this point if you haven't chanced upon the phenomenon that is 'Here Comes Honey Boo Boo') taking a risk on her special day in an orange and camouflage number.

To celebrate this remarkable feat in an age of Bridezillas and wedding planners, here are some more celebs who chose to go unconventional when it came to saying 'I do...'
