Diddy's train isn't ready to leave just yet.

The Bad Boy mogul revealed this morning to BBC Radio 1's Scott Mills that his fifth studio LP, "Last Train To Paris" has been pushed back to September 20.

Diddy's original release date for the project was June 28, one day after the 2010 BET Awards, where he will perform with his Dirty Money crew.

Thus far, three singles have been released from the opus, all with visuals. The latest single, "Hello, Good Morning," features T.I. and Rick Ross.

Nicki Minaj, who is rumored to be Diddy's new client under his Bad Boy Management umbrella, will appear on the remix, which will be released in the coming weeks.

Reasons for the push back have yet to be revealed, but over the past two months, several tracks from the project, including an unfinished collaboration with Jay-Z and Swizz Beatz, have leaked prematurely.
