One might think that Vin Diesel has enough franchises on his plate, with Fast & Furious 7 hitting theaters next year, and the actor revealing yesterday that Universal Pictures is interested in making a sequel to last year's sci-fi thriller Riddick. It seems he has room for one more franchise, with the actor revealing that the script for his long-gestating sequel XXX: The Return of Xander Cage will be completed next month, and that Katy Perry has been suggested as the sequel's leading lady.

Here's what the actor had to say on a post to his official Facebook page, and you can CLICK HERE to watch a video where he thanks the fans for Riddick's success. He also shows off a Riddick-themed "MouseBoard" series of images, where he is seen dancing to Katy Perry's song "Dark Horse."

"As you know, the new XXX script finally comes in next month... and just this morning people are suggesting Katy Perry as the new X girl.

P.s. Who would you like to see me work with this year?"

Of course, it isn't known if an offer is even out to Katy Perry for the sequel, or if she would even be interested in starring. It's clear, though, that the actor is a big fan of the singer.

We haven't reported on XXX: The Return of Xander Cage since April 2010, when original xXx director Rob Cohen became attached to direct. It isn't known if the filmmaker is still involved in the project, or who is now working on the script. John D. Brancato and Michael Ferris (The Game, Terminator Salvation) were originally attached to write the script, but since so much time has passed, their involvement is questionable as well. Our report from April 2010 revealed that the story centers on Vin Diesel's title character, who is left for dead but comes back to execute a mission tailor-made for his unique skills.

Vin Diesel starred in 2002's xXx, which earned $277.4 million worldwide. The 2005 sequel XXX: State of the Union starred Ice Cube as another XXX secret agent, Darius Stone, although it fared significantly worse, earning just $71 million worldwide.
