Former Strictly presenter and Traitors host Claudia Winkleman has teamed up with other celebrities to support the British Red Cross. The British Red Cross is a charity that helps people in need across the UK and the world. They have created a new t-shirt called Here for Humanity to raise money and spread a message of kindness. The t-shirt was designed by Charlie Mackesy, a famous illustrator. Claudia Winkleman says it's an honor to wear the t-shirt. Other celebrities like Jamie Oliver, Julia Roberts, and Alison Hammond are also supporting the cause. They want to show that we are all connected and that kindness matters. The money raised from the t-shirt sales will help the British Red Cross do their important work.
