[Photos] Post #BirthdayCake, Photogs Catch Rihanna Lookin’ Fly & Comfy

One day after celebrating her 24th birthday and dropping the highly anticipated “Birthday Cake” collab w/ her ex, Chris Brown, Rihanna was spotted leaving her London hotel. Rocking a quite comfy jersey dress, Rihanna posed w/ a few fans before jetting off. We hear she performs tonight at the BRIT Awards. Anywho, check the pix.
