Toby Keith's 11th annual Toby Keith & Friends Golf Classic is happening this weekend (May 16 and 17) in Norman, Okla., with all of the proceeds benefiting the OK Kids Korral, a free home away from home for pediatric cancer patients.

The two-day event kicks off on Friday night with an invitation-only evening at the Riverwind Casino, where 750 guests will bid on high-dollar auction items, including an African safari, a stay at the Lodge and Spa at Brush Creek Ranch in Wyoming, a trip to Lake Tahoe and a bull elk hunt. Several celebrities -- including Kurt Warner, Alice Cooper, Jason Aldean, George Strait and Derek Jeter -- have also donated autographed memorabilia as well.

Saturday morning, 200 golfers will have the opportunity to hit the greens with numerous stars as well, including Dermontti Dawson, Tony Casillas, Roy Williams, Sam Bowie, Nancy Lieberman and Red Steagall. The event concludes with a Built Ford Tough Shootout, with one lucky winner taking home a brand-new Ford truck.

The OK Kids Korral was started by the Toby Keith Foundation earlier this year, after the singer spent years trying to make his dream come to fruition.

“We’ve been working on the Korral for 10 years and we’re finally going to open,” Keith said of the occasion. “Thank you to all of those people who have supported us over the years. Ten years goes by fast when you are working toward a goal this big.”

More than 75 families have visited the OK Kids Korral since its opening. Donations to the center can be made here.
