Kesha is lending her vocals to a new song from Pitbull called "Timber." 

The pop singer and rapper spent the summer co-headlining a summer tour, in support of Kesha's Warrior and Pitbull's Global Warning, both released last November.  The Dr. Luke-produced "Timber" will be featured on the rapper's next release, and will be available to download on iTunes starting October 13th. 

The song was unveiled on Monday's "On Air with Ryan Seacrest."  Pitbull told the radio show that he and Kesha "hit it off" while on tour, adding "what better than to have a crazy, sexy, cool beautiful woman on it with me."
