Tim McGraw will host Saturday Night Live for the first time on Nov. 22. McGraw is promoting a new movie, Four Christmases, which will be released on Nov. 26 with co-stars Vince Vaughn, Reese Witherspoon and Jon Favreau. "I'm looking forward to hosting the show," said McGraw. "I'm not exactly known for my comedy, but then again if you've been to one of my shows you might feel differently. Hopefully hanging around Vince Vaughn, Reese Witherspoon and Jon Favreau is good training." Other country stars who have hosted Saturday Night Live include Johnny Cash, Willie Nelson, Dolly Parton and Garth Brooks.
