Input: It was a real fairytale wedding when Debra Mundy and Mervin Rider finally tied the knot after being together for 23 years. But the Queensland couple made sure the wait for their big day was well worth it, and memorable for all involved, as they celebrated their union dressed as popular animated characters Princess Fiona and Shrek. A star-studded guest list attended the matrimony of the two ogres, including the Gingerbread Man, the Little Red Riding Hood, the Big Bad Wolf and Prince Charming. And of course, Shrek's loyal sidekick was by his side as the best man. It's been a long time coming for the couple as Ms Mundy, 41, admits that she had declined many proposals from Mr Rider, 38, over the years.Debra Mundy and Mervin Rider held a Shrek-themed wedding on SaturdayThe bride arrived in a horse-drawn carriage as Princess FionaWhile the groom was dressed as Shrek for his big dayThe Queensland couple tied the knot after being together for 23 yearsAbout 40 guests attended the wedding and dressed up for the event
