Singer says supporting Alanis Morissette is nuts
"It's unbelievable, I can't believe it. I never thought I'd get to support her."
Megan Wyn, 20, from Anglesey, said her mum cried when she told her she would be supporting superstar Alanis Morissette.
The indie-pop artist is still in shock as her mum is a big fan and plays her songs in the house.
The Grammy award-winning Canadian will perform in Cardiff this summer and demand for tickets has been so high the gig has been moved to a bigger venue.
"We're just going to put on the best show we can," she said.
