Rihanna is back at work. She appeared in Philadelphia last night

Rihanna appeared to return to form after missing two concerts because of illness. She rocked out the Wells Fargo Arena in Philadelphia with no sign of the laryngitis and flu that floor her before her Diamonds Tour could get on the road.

She only got off one show in Buffalo, New York last Friday, before canceling follow-up appearances in Boston and Baltimore. No word yet on whether those shows will be rescheduled.

Concert promoter Live Nation told fans to hold onto their tickets pending a rescheduling of show dates. The promoter advised that “Rihanna was still recovering.”

But she didn’t just limp around the stage. She gave a high-energy performance that included several costume changes and a retinue of her classic hits. She wore a jumpsuit with a plunging neckline, a two-piece red dress with a long maxi-skirt and a mini-dress.

Rihanna was heartbroken by the cancellations. “#BOSTON this is the hardest thing for me to deal with! I feel like we’ve been waiting on this day forever, and I’m hurt that I let you down.”

“I hate disappointing people that never ever let me down!! I’m so embarrassed about this! Thank you for your prayers and well wishes! #DWT,” she added.

Rihanna is definitely one of the hardest working singers in show business. She’s produced almost an album a year for the last seven years and has toured relentlessly.

“Thank you so much, tonight was an incredible experience,” she told the crowd. “I will never forget this show, ever. I can’t wait to come back here. Philadelphia, I will always come back here.”

Maybe, she just needs to cut back on those nasty blunts she smokes in all those Instagram photos. The 27-city tour arrives in New York today. She’s supporting her seventh album, Unapologetic.
