Still feeling under the weather, Rihanna has cancelled her Tuesday night (March 12) performance in Baltimore.

The cancellation comes days after the "Diamonds" diva was forced to postpone her Boston show after coming down with laryngitis and the flu on Sunday.

Starting her "Diamonds World Tour," Rihanna performed at the First Niagara Center in Buffalo, New York on Friday (March 8).

The "Stay" songstress went through a variety of costume changes, including a mid-riff baring sleeveless red top with matching skirt, a color-block bustier and leather pants combo, a very short dollar-patterned dress, and a short-sleeved black oversized top with nearly waist-high white leather boots.

Bringing an end to her short visit to the UK, Rihanna left her luxury hotel in London, England this morning (March 5) on her way to Heathrow International Airport.

The “Russian Roulette” songstress donned a fur-hooded winter coat with jeans and tan leather boots as she caught her ride to the airport following a whirlwind promotional stay in the English capitol city.
