Get the next Object Id before create the object for a Model Rails

I have a Model I need to get the next record id which is going to be create before create that object in my model like:

MyModel.last.id #=> 10
MyModel.last.destroy
MyModel.last.id #=> 9, so (Model.last.id + 1) would be 10... but...
MyModel.create  #=> 11, my next id was actually 11

Can you please suggest a better way to solve my problem?

Thanks
