Bridesmaids belt out surprise medley at sister's wedding

Kelsey and Maddie Hallerman delivered a performance to remember at their sister Caitlin’s wedding in Lake Tahoe, California.

The co-maids of honour wanted to do something special for their sister's wedding to her news husband Johnny Weaver, so they took a medley of popular songs and customised the lyrics to fit the occasion.

Speaking on their performance to buzzfeed.com Maddie admitted: "We didn't hold back (sorry to everyone's eardrums). What we lack in talent we make up for in enthusiasm."
