Did you buy them at the same time? If so they are likely brother and sister and you should never mate hamsters who are this closely related. You could end up with badly handicapped babies and you would not want that to happen would you.
Separate them quickly Cady. They are likely still OK together as they are still young in which case they are too young to be breeding anyway.
All Teddy Bear or Bear hamsters are Syrian Hamsters, often long haired and these names are just labels given by pet shops to sell them at higher prices.
