The Friends in Low Places hitmaker was greeted by cheers from youngsters and their families as he pulled up to the Riley Hospital for Children in Indianapolis in a race car driven by IndyCar star Charlie Kimball as he prepared to cut the ribbon to open the Child Life Zone, which was funded through his Teammates for Kids foundation.

At the opening ceremony, Brooks gushed about the "miracle" play room, which was designed to help sick kids forget their health troubles and just have fun. The large space features a billiards and foosball table, video games, an arts and crafts area and a special recording studio for wannabe singers to lay down their vocals, reports the New York Daily News.

Addressing the crowd at the event, the father-of-three said, "What you're witnessing here in these zones is truly a miracle. It's a place in a hospital where no doctor and no needles are allowed. It's a place where a kid gets to be a kid."

Brooks later mingled with fans, posing for photos and signing autographs, and one lucky patient, 11-year-old Chloe Alexander, made his day by telling reporters she was grateful to the star for taking the time to lift her spirits.

The pre-teen, who had the singer sign a cowboy hat for her, says, "I told him that my dad will be jealous (of her autographed memorabilia) and that it was so nice to meet him. He said that he loved me. He also said that I have a great spirit."

Brooks co-founded the Teammates for Kids charity in 1999 and has since helped launch 11 Child Life Zones at medical centres across the U.S.
