After securing a gold-selling debut album ('Cole World: The Sideline Story') and a Grammy nomination for Best New Artist, J. Cole reached another milestone today (Feb. 22): he accumulated two million followers on Twitter. In celebration of that social-media feat, the 'Work Out' rapper released a free downloadable track called 'Grew Up Fast.'

Produced by Canei Finch, the song boasts a soulful David Ruffin sample and a 808 drum kick. On the track, J. Cole takes shots at sensitive rappers who have gone soft with their rhyme flows. "Y'all got way too electro / Damn near techno / Half way homo / Way too metro / Hennessy XO / Cole flow special / Style like Tribe Called Quest meets Death Row," he raps.

The song is available for download at J.Cole's blog DreamVillain.net.

Meanwhile, J. Cole is not finished promoting his 'Sideline Story' album, just yet. The North Calackie MC just completed a video for his next single, 'Nobody's Perfect' featuring Missy Elliott. "It’ll probably be my best video yet, visually,” he says about the production. "Man, just to have Missy on that set and to see her singing the song that I wrote. It’s Missy, I don’t think people really understand; that’s my era and how I look at her and how creative she is and her and Timbaland and the things that they did. That was a beautiful moment right there.”

In addition, fans can catch J. Cole this spring on his Campus Consciousness / The Sideline Story Tour. The 17-city trek starts on April 11 in Kingston, R.I., and ends on May 4 in South Orange, N.J.
