Yes, she may be Rupert Grint's younger sister, but we can't help but think it's Samantha Grint's name you'll be hearing plenty of pretty soon.
Steve met her at a music showcase he was hosting earlier in the year and invited the 15 year old singer/songwriter in to play live in the studio.
Yep, 15, talented, stylish and cool. We really need to stop getting people like this in at JACK as we just look rubbish and failed in comparison.
Anyway, listen again as she chats about music and having a famous Harry Potter star brother and listen to her brilliant track 'Un-Ordinary' played live.
