Mortal Kombat PS3 and PSVita Online Question

Hey guys. I've tried to look around on the internet, but couldn't find an answer so I thought it was time to just post it. Basically my question is simple. If someone has the PS3 version of Mortal Kombat and someone has the PSVita version of it, are they able to play online together with the different versions of the game or do both versions have their own separate servers?
 
They're separate. MK9 & MK9 Vita are two different games. Vita version has costumes that the console version doesn't.
