Annelies will sing the national anthem prior to the 2016 Capital One Cup Final between Liverpool and Manchester City.
The 21-year-old started performing at an early age and has already appeared at Wembley Stadium, as well as the Millennium Stadium and Twickenham.“I am so excited and honoured to sing the anthem at Wembley at such a prestigious and high profile event,” she said.
“This definitely is a once-in-a-lifetime opportunity for me.”
A member of the London College of Music, Annelies performed ahead of the 2015 Sky Bet League 1 Play-Off Final between Preston North End and Swindon, and also appeared at Twickenham in March 2014, when she was proud to sing the Welsh National Anthem before Wales took on England in the 6 Nations.
