As we previously reported, the [uuid=40e86b6b-3569-4110-98b2-ed9b70b18420]Bajan babe had to postpone gigs[/uuid] in Boston and Baltimore after falling ill - with the 25-year old later tweeting she was "embarrassed" about scrapping the concerts.
However, RiRi was back on form last night, taking to Twitter to declare that Philadelphia was one of her favourite places to perform.
The Stay singer posted: "One of my favourite cities in America #PHILLYnation #DiamondsWorldTour WE BACK!!!!"
A source close to Rihanna has since told Hollywood Life that she hopes to give fans in Boston and Baltimore 'a little extra' when the gigs are rescheduled.
The insider told the website: "She feels awful she had to cancel two f**king shows but it wasn't nothing she could do about that.
"She hopes her fans give her another chance and you know she's going to give the crowd in Boston and Baltimore a little extra!"
