The Lollipop Theater Network, which provides movies and other forms of entertainment to children facing life-threatening illnesses, is hosting a celebrity auction to raise money for the worthwhile cause, and Nashville's top entertainers are coming out in full force to contribute. Tim McGraw, Lady Antebellum, Keith Urban, Billy Currington, Joe Nichols, Kellie Pickler, Craig Morgan, Montgomery Gentry, Heidi Newfield, Michael W. Smith and Amy Grant are all donating concert tickets plus a meet-and-greet to the Lollipop Theater Network, with several bids already approaching almost $1000.

Other donations include tickets to a Yankees game, a meet-and-greet with the Broadway cast of 'Elf,' Andy Warhol Campbell's soup bowls signed by Sigourney Weaver, Matthew Broderick and Kevin Kline, an autographed 'Twilight' poster, a watch signed by Anne Hathaway, and several more items.

The Lollipop Theater Network, which began in 2001, has allowed children to preview hit films such as 'Karate Kid,' 'Cloudy With a Chance of Meatballs,' 'Harry Potter and the Half-Blood Prince' and 'Despicable Me.' In addition, several high-profile celebrities, including Taylor Lautner, Jennie Garth, Emma Roberts, Steve Carell and Chace Crawford have all taken time out of their busy schedules to pay visits to the children in the hospital.

The auction is being hosted by CharityBuzz. Bid on your favorite items here.
