The stars of Game of Thrones are joining up with Coldplay to make a musical for Red Nose Day.
It includes Jaime Lannister (Nikolaj Coster-Waldau) performing a love song to his twin sister Cersei.
A YouTube video yesterday shows stars of the show, including Kit Harington and Iwan Rheon, practicing.
And an excerpt on on Coldplay's Facebook page has Tyrion Lannister (Peter Dinklage) singing this:
Some people's parts are not very long...
You can watch an excerpt of his song here.
And here's Jaime's song for Cersei (and his hand).
Comic Relief will be broadcast tonight on NBC 8/7c.
