what is my rabbit's breed?

This is Tilly, she's about 8 months. We re-homed her after another couple couldn't find time to look after her.
We were told she is a false netherland dwarf rabbit but I really just wanted to find out for definite!
Also she's always been on her own so I also wanted to know the breed to then decide if she would accept another rabbit or if she's happy on her own.
Any ideas or help would be much appreciated (:
