We've heard of runaway brides, but what about a runaway flower girl?

As Katie and Tom Quirk said their vows at Albert Park Lake in Melbourne, Australia, their three-year-old niece, Chloe, made a mad dash in the background.

Hilarious footage posted to the Burgess Video Facebook page shows the little girl whiz by the couple, with her mother in hot pursuit.

"I was facing the direction Chloe was running from, but because I was looking at Tom. All I saw was this flash of white all of a sudden in my peripheral vision," Katie told Daily Mail Australia.

"And then I saw my sister-in-law madly running past and I was like, 'Did that really happen?' ... It will go down as probably one of the funniest moments anyone we know has witnessed at a wedding."
