Pregnant British pop star Rochelle Humes and her singer husband Marvin spread a little festive cheer on Sunday (02Dec12) by attending a Christmas party for sick children in London.

The Saturdays singer, who is due to give birth next year (13), joined her partner and his JLS bandmates to meet youngsters at a hotel in the U.K. capital.

The stars played games with the kids at the event, staged by the Rays of Sunshine organisation, which grants wishes for sick children.

The mother-to-be then uploaded pictures from the bash to her Twitter.com page.

Jls star Aston Merrygold tells Britain's Daily Star newspaper, "If you can give up a couple of hours of your time to help these kids it's brilliant. They are incredible, and it's wonderful to be able to put a smile on their faces."
