Jennifer Aniston has lent her support for charity in a new ad shown on US TV. The Friends star, 38, is one of the celebrity names helping generate interest in the 2007 Thanks and Giving Campaign for St. Jude Children's Research Hospital. Other stars supporting St. Jude's, include funnyman Robin Williams and Spanish actor Antonio Banderas. During the advert Aniston looks radiant and stunning as she introduces Bryce, a young boy who was diagnosed with a kidney tumor and was cured thanks to the organization. She kisses the young boy on his nose, after he tells Aniston he will be donating money to the charity, so other kids can benefit, and she makes a joke about putting lipstick on his face. (little does that boy know he could sell that lipstick residue on Ebay!) St. Jude Children's Research Research Hospital aims to find cures and save children from illness, and Aniston previously supported St. Jude's in 2006 by modeling a specially designed DKNY T-shirt with the words "Give Thanks" spelled with rhinestone across the front.
