Here's what James McAvoy is doing with his signed shirt from the Oscars

James McAvoy is donating his autographed shirt from the Oscars to charity.

The "Split" actor made headlines after last month's Academy Awards when he hit the red carpet at the Vanity Fair Oscars Party in a white dress shirt that had been signed by a slew of celebrities in red Sharpie.

Bris Larson, Samuel L. Jackson, Michael B. Jordan, Frances McDormand, Charlize Theron and Melissa McCarthy are among the names of the famous faces who autographed McAvoy's shirt on Oscars night, and the actor is now giving up the instantly-iconic piece of clothing for a good cause.

McAvoy announced this week that he's launching a sweepstakes to win the shirt in an effort to raise money for Ronald McDonald House New York, a charity for childhood cancer.

"Welcome to my Oscar shirt sweepstakes," he said in the announcement video. "I went to the Oscars, I found a Sharpie and then I asked lots of presenters and winners and nominees and just famous people to sign my shirt."

"There are Amy Adams and Charlize Theron and Melissa McCarthy and Sophie Turner and lots of other people on here," he continued. "The reason I am sweepstaking this shirt is because I'd like to raise an incredible amount of money for an incredible charity called Ronald McDonald House in New York."

"They provide care and accommodation for children and their families battling cancer. Children from all over the world, [and] families who desperately need to be with their children through that difficult time, which is not always provided," he finished. "Please please please, buy some tickets try and get that shirt. It will be cleaned -- unless you don't want it to be, which is weird, but it's for a good cause, so we'll understand."

Fans can donate to the sweepstakes here -- just a $10 donation garners 100 entries to win the shirt! The winner will be announced in May.
