Slow Hands Niall Horan
Labrinth came to visit Capital, so we got him pedalling!
Labrinth performed at the O2 Academy on Monday night, so we got him in on Tuesday's show.
After telling him that he was our favourite guest ever - and generally showering him with compliments because he's awesome - we decided to make him do some work!
All this week, we are cycling the length of the M6 for Help a Capital Child, which is supporting the Teenage Cancer Trust to raise money for to help teenagers living with cancer.
Hear what we got up to with Lab here, and if you can, please don't forget to donate!!!
