For serious... Rihanna needs to get those nails clipped ASAP. My dogs nails are shorter than that.... I can recommend a good groomer if need be.
I understand she is known for being a trendsetter but this trend needs to be scratched off the list. That can't be safe. Girlfriend needs a nail file... stat. Unless she grew those weapons for self defense purposes... it's not acceptable RiRi.
If you're not dating that handicapped boy turned rapper from Degrassi anymore.. I have a match made in heaven for you... his name is Edward Scissorhands.
