Toby Keith and Julianne Hough are the latest in a long list of country stars who are digging into their wallets to help the residents of Haiti after a January 12 earthquake ravaged their country.

Toby is partnering with Project Haiti -- a collaborative effort effort between Can-Do and Livin' the Music -- to ship relief supplies to the Haitians. The generous singer has donated seven tractor-trailers that will sit at a designated spot in Nashville, Tenn. until Feb. 2, when the supplies will be delivered directly to the Haitian capital of Port-Au-Prince.

Meanwhile, Julianne has generously contributed to Plane to Haiti, a committed effort to send more than three tons of medical supplies, plus doctors and nurses, to the Haitian people. Other artists joining Julianne in supporting the cause include David Archuleta, Scott Stapp, New Kids on the Block, Godsmack and many others.

Several other country artists have donated their time and talents to help the people of Haiti. Taylor Swift and Keith Urban both participated in the Hope for Haiti celebrity telethon last week, led by movie star George Clooney. Lady Antebellum lead signer Charles Kelley made a financial donation. Martina McBride and Tim McGraw partnered with the American Red Cross to raise money. And Big Kenny traveled with a team of doctors to offer assistance firsthand, and experience he describes as "heart-sinking."
