Rapper Lil' Wayne has pushed back the release of "Tha Carter IV" once again.  The much anticipated album will now arrive in stores August 29th instead of June 21st, the latest release date to be changed.  The album has now been pushed back four times, without much of an explanation accompanying any of the delays.  The rapper has been busy, however, since his release from a New York jail last November.

Three singles from the eventually-to-be-released album have debuted, and Wayne has been on the road pretty much non-stop.  Wayne will join Drake, Chris Brown, Wiz Khalifa and many more at Hot 97's Summer Jam this Sunday (June 5), and will continue his "I Am Still Music" tour with Rick Ross, Keri Hilson, Lloyd and Far East Movement beginning on July 13. Fans will also be treated to a preview of "The Carter IV" when MTV airs Lil Wayne's "Unplugged" performance on June 12.
