A little bronchitis and tour delays are not going to slow down Rihanna for her 28th birthday. The bajan beauty was spotted over the weekend twerking up a storm for her big day. RiRi hit up Twitter to thank fans for the B-day love, “Thank you for blessing me with all this love on my birthday! Yesterday was special! One Love Always.”And for those you you waiting Rihanna also released her new video ‘Work’ featuring Drake. Warning tons of grinding!
