Gwyneth Paltrow hosted a festive charity dinner in London on Monday night (25Nov13) to raise money for underprivileged kids. The Iron Man star teamed up with fashion designer Matthew Williamson to host the event at Aqua Shard to bring in money for the Kids Company organisation. The event featured a Christmas tree decorated with baubles specially designed by stars including actress Sienna Miller and singer Mary J. Blige. The sparkly ornaments will be auctioned off to raise money for the cause. After the event, Paltrow took to her Twitter.com page to thank Williamson for his help, writing, "Thank you Matthew Williamson for supporting Kids Company UK."
