Are Kristen and Nikki Still Game for Prison Flick?

One of these Twilight babes is backing out of their joint passion project

Kristen Stewart says Breaking Dawn plans are "still not concrete" (trust, it will be two movies with a fall start date), so we were curious to know what projects outside of Twilight she's got her eye on.

The wild-sounding K-11 has supposedly been in the works for a while, with Stewart's mom set to direct and Kristen and sometimes BFF Nikki Reed set to star as transsexual and transgender prisoners.

But it seems like all is not going according to plan, as we learned when we caught up with the tiny babe last week.

Read on to hear Kristen fill us in on the latest K-11 update and find out which babe isn't going to be a part of the film after all...

"I can't wait for K-11 to happen," Stewart told us, super enthusiastic when we asked about her passion project. "It's just one of those things."

Hmmm, one of those things? Hate Hollywood-speak sometimes! Does that mean it's definitely a go?

"I hope so," replied Kristen. "It's an independent movie. That's always hard, especially right now. It's really hard to get them made. But we're trying!"

However, not everything is going according to what was once planned. We're told Nikki Reed will not be part of this side project.

"She's not involved due to her schedule," a rep for Miss Reed told us when we asked if Nik was still onboard.

So that leaves us with a few ways to take this, since according to Kristen, there is no schedule yet:

1. Lies! K-11 is happening now, but K.Stew is staying mum while details get sorted out.

2. The up-in-the-air plans are too fuzzy for Nikki's schedule, so she told Kristen & Co. to figure it out without her.

3. N.R. isn't going to be part of the flick no matter when the damn thing gets made

Guess away.

As for what is a sure thing? We hear both Nikki and Kristen will be back for Breaking Dawn, which will probably start shooting this November (according to Stewart herself).

In the meantime, both gals are keeping their plans (like their love lives) until fall very hush-hush.
