Hip-hop heavyweight Lil Wayne has delayed the release of his highly anticipated mixtape so he can add an extra track to the compilation.

The rapper was due to put out Dedication 5 on Friday (30Aug13) but he decided to hold fire after a last-minute flash of inspiration.

A post on his label's website YoungMoney.com states, "The release of Dedication 5 has been temporarily postponed for a short period while Wayne puts finishing touches on it - including another new song. Stay tuned for an update."

The Lollipop hitmaker took his Twitter.com page to explain the situation to fans ahead of his gig in Concord, California, on Friday night.

He tweeted, "I'm turning d5 in to (producer) DJ Drama when I get off stage. Had a few new entries at the last minute that's too dope to miss da tape (sic)... gimme a min (minute)."
