Fountainhead says it 100% correct.
OK, they may not find out, you get the visa granted, and congratulations from all. Your gamble to be together sooner rather than later paid off.
However, if they investigated, checked your NI contributions for the next 2 months and found you were not working. You will not only be refused, but they will review any subsequent application with suspicion.
I know you want to get this done sooner rather than later, but you are gambling by telling lies. Better to either apply stating the truth (that you are currently unemployed), or wait until you have a new job.
Just my opinion.
