Hard at work on her upcoming album, Rihanna was spotted arriving at Milk Studios in Manhattan’s Meatpacking District on Monday (October 19).

Still sporting that interesting ‘do of hers, the “Umbrella” songstress hurried inside dressed in all black paired with brown shoe booties.

Keeping her fans in an exciting suspense, the singer’s Web site now features a countdown clock letting everyone know that on October 20 at 11:23am something big is going to happen.

There’s no exact word on what that will be, but there are assumptions that the singer will release her first single off her forthcoming album, which is reportedly due out on November 23.
