Tim McGraw Collaborates With Chris Brown

R&B/pop superstar Chris Brown is testing his country crossover abilities with help from Tim McGraw. The two have recorded a song together called 'Human.'

"It's incredible," Brown tells Billboard. "I wanted to do something more along the country line. That's a bigger and different audience for me."

McGraw has already expanded his audience outside the country world. He recorded a hit song with R&B star Nelly, 'Over and Over,' in 2005. He also wrote and recorded the song 'Nine Lives' with hard rockers Def Leppard this year.
