Maid of honour goes viral with special performance of ABBA's 'Gimme! Gimme! Gimme!' at wedding

This maid of honour made her best friend feel like a bonafide Dancing Queen when she pulled off the most fabbalous toast ever.

Instead of delivering a traditional wedding toast, Lauren O'Brien had everyone in stitches when she took to the dance floor during the reception to sing a special version of ABBA's classic 'Gimme! Gimme! Gimme!'

Best friends since they were both little girls, O'Brien knew only too well about bride Natasha Long's life-long obsession with the Swedish supergroup.

So she rewrote the lyrics to the 1979 hit song to tell the tale of their relationship and how she and her future husband Bradlee Harker first got together.

A video of the performance, which was uploaded to social media, has since gone viral with over 10,000 views. 

Very cool!
