AceShowbiz - Chad Michael Murray, the beloved "One Tree Hill" alum, is getting fans hot and bothered with his latest project: a 12-month calendar that features him in various states of undress. The steamy calendar not only serves as a treat for Murray's fans but also benefits a worthy cause.

Proceeds from the calendar will be donated to St. Jude's Children's Hospital. For $59.99, fans can purchase an autographed version of the calendar on Murray's website.

The calendar features 12 photos of Murray commemorating each month in a playful and alluring manner. In January, he poses shirtless with a undone tie and trousers. February sees him going shirtless again in red boxer briefs, holding a heart-shaped pillow and Cupid's bow.

For March, Murray celebrates St. Patrick's Day in a green tie and sweats and commemorates March Madness with a basketball. In April, he gets into the Easter spirit with bunny ears. May brings a dreamy shirtless photo of him presenting a bouquet of roses.

June sees Murray graduating shirtless. In July, he proudly displays the American flag over his bare upper body. August marks his birthday with a festive cake in hand.

In September, Murray kicks off football season helmet-clad. October features a sexy Halloween costume complete with a Jack-o'-lantern. November finds him shirtless preparing the Thanksgiving turkey. And in December, he decks the halls without a top.
