Last night, (after months of working on her partnered clothing line) 24 year-old Rihanna unveiled her "River Island Collection" at London Fashion Week. 

Check out the pics below:
Here's what she had to say about the collection:

"Launching at London Fashion Week is a dream come true for me," said Rihanna. " I have wanted to design my own collection for a long time and to present my collection for River Island alongside all of the other great design talent at LFW is a real privilege. I can't wait to see the reaction from my fans and the fashion press!"
