"I may not be able to do the amazing things that the staff at the hospital can do, but I can help raise much-needed money and public awareness that is essential for them to keep helping children," Cat said as she launched the appeal, which continues throughout February to raise funds for research into, and the treatment of, childhood cancer.
And all you need to do is treat yourself to a new lippy. Clinique - an appeal partner with GOSH - will be donating £1 to the appeal for every lipgloss and lipstick sold throughout February, matched by £1 from House Of Fraser when the two cosmetics are bought from House Of Fraser stores.
The range of lip cosmetics will include the new, limited edition 'Kiss It Better' Lipstick - rich, creamy, long-lasting lippies available exclusively from Clinique counters at House Of Fraser.
