Simple Question but eh

I didnt want to post a whole new thread on this but i guess i have too.
I was hoppin around and i felt somethin was up with my seat. When I looked there was a small gap between the front of the seat post and the seat. I went home and took off the seat and 3 of the 4 bolts underneath it were loose, is this right? Also there was a crack in it like the picture, so do i need a new seat? Or can i fix it somehow?

                                                                                   Thanks
                                                                                    Brian

Edit:O ya the seat is a kh.

Oops i just realized i drew the orange in the wrong place, its in the front of the seat not in the back.

looks like its time for a new saddle

Theres no way I can fix it?
