Dierks Bentley's upcoming 'Miles & Music For Kids' charity ride and concert keeps adding star power, thanks to the generosity of a few of country's biggest artists. Dierks, already joined by label mates Darius Rucker and Eric Church, recently announced the addition of Wynonna, Heidi Newfield and Michelle Branch.

"My idea of the perfect Sunday afternoon includes live music, motorcycles, beer and football ... But you also have to have girls -- can't forget about them," Dierks jokes. "It's awesome that Wynonna, Michelle and Heidi want to come help us raise some money that day. It should be a blast."

The October 11 event, which includes live music, the bike ride and tailgating before the Tennessee Titans play the Indianapolis Colts, benefits the Monroe Carell Jr. Children's Hospital at Vanderbilt University. This year, for the first time, Dierks decided to expand the event, by partnering with the Children's Miracle Network and taking 'Miles & Music' to six cities across the US. Since the program began three years ago, more than $500,000 has been raised for the hospital.

Dierks must be in the giving mood. Only two days after his charity ride, he will donate his time for another great cause, singing in an all-star concert benefiting the Country Music Hall of Fame and Museum. Headlined by Keith Urban, the Oct. 13 show will also include performances by Jason Aldean, Faith Hill, Lady Antebellum, Taylor Swift and Vince Gill.
