This private moment of Britney (filmed by hubby Kevin Federline) shows what a class act she is.  She whines about how ugly she is, then she burps, all the while acting — I don’t know — stoned, I guess.  She’s swatting at imaginary fairies or something.

But the best part comes at the end:

Britney: Have you ever seen "Back To The Future"?

Kevin:  Hm-mmm.

Britney: Is that possible?  To time travel speed?

Kevin:  No.

Britney:  Yes it is, Kevin.

Kevin:  Okay, but not that we know of.

Britney:  I think people can do that, and I think some people are ahead of us.

Very true.  I think everybody is ahead of you, Britney, evolutionarily speaking.
