Rapper T.I. is saying 'Hello' to the haters on his new track, which is produced by Pharrell Williams and features Cee Lo Green on the hook. The smooth tune will appear on the Atlanta rapper's upcoming album 'Trouble Man: Heavy is the Head,' which arrives in stores on Dec. 18.

Despite the laid-back productions on the song, T.I.'s verses are hard-hitting as ever as he reminds the naysayers he's not looking at them, he looking past them -- while driving his luxurious new car. "Mashin’ in the fast lane / Envy in my rearview / Mills in my windshield / Keep ‘em in a clear view," he raps.

Green is in the passenger seat enjoying the ride and advises Tip to "Push that peddle to the max / Count the money in your lap / And put jealousy in your rearview."

On the second verse, the Atlanta rhyme-slinger continues his boasts vowing to stay on his grind forever. "I hustle hard, forever shine / Pay haters no never mind / Won’t stop until we poppin’ bottles at the finish line," he spits.

The song is a smooth departure from his usual trap music bounce and it gently caresses the ears with its melodic productions.

T.I. has several collaborative tracks on the 'Trouble Man' album including songs with Andre 3000 ('Sorry'), Lil Wayne ('Ball'), Pink ('Guns and Roses'), R. Kelly ('Can You Learn') and A$AP Rocky ('Wildside').
