Britney Spears has a back-up plan for that superslim off-chance that her Vegas residency (and the rest of career) ever goes to sh-t. Apparently, she'd just love to be a nanny to Brad Pitt and Angelina Jolie's kids.

Now, either she's hoping to get an in-the-flesh glimpse at some of that hot Brangelina chemistry action (at least, on-screen), or she's even kookier than we thought. We'd honestly prefer the latter of the two because BRITNEY, B---H.

"I've met Brad Pitt once but I'd like to meet him again. And I'd like to become their nanny,"

she revealed on "Good Morning Britain." "That sounds fun to me."

And you know what? The job probably pays pretty well, considering there are six little ones to account for in the Jolie-Pitt crew - Maddox, Pax, Zahara, Shiloh, Knox, and Vivienne. (Even so, we highly doubt it adds up to that multi-million dollar deal she's got going on over in Sin City. So, you know, don't quit your day job or anything.)

Another career the long-reigning Princess of Pop could see herself doing is teaching. And she bases that off of her own experience doing homework with Sean Preston and Jayden James. Of course.

"I'd probably be a teacher or anything relating to the kids or teaching at a dance studio with a bunch of kids," she said. "They go to a really hard school, and this week we had three hours of homework ... Some of it is hard for me. Next year when he is in fifth grade, he's going to be doing pre-algebra, and I'm taking classes so I know how to do it."

We can totally picture it now ...
