Help. My wife spilled paint in the back seat of the car [PIC]

We wiped most of it out with old sheets, now what? http://imgur.com/IKf8Z.jpg

*update - we got it mostly under control - http://imgur.com/OIimR.jpg Thanks so much for all your help reddit, you guys are great... (The towels are there cause the seatbelt clips are still leaking a little)

*Final update - Had a few ask what worked to get it out - so from pic 1 to pic 2 -a big bed sheet to literally 'push' as much of it out the side of the door, then wipe as much out with another sheet -more sopping up with paper towels to try and absorb whatever possible without rubbing it into the seats. -hot water and towels to get is much out from the fabric as possible - our biggest help here is that we tackled all this while it was fresh and still wet. There is about 4 inches of cushion/padding underneath that it had started to soak through that hot water and a wet/dry vac was able to lift out. (It wasn't soaked through the whole thing - just the top half-ish of it...) -The edge of the paint line where it was thinnest had started to dry but came off with some towel rubbing still. The seat is still wet, I left my windows cracked to keep drying out, but it actually looks even better now that the seat has started to dry. I might post a final pic if anyone is interested, otherwise just know that it looks back to normal pre-spill conditions with the white line even gone now. Thanks again everyone so much for your help, the serious ones and even the smart ass ones that helped me laugh and keep a cool head about it all...
