Rihanna didn’t show any signs of sickness as she celebrated her 28th birthday on Saturday.

As seen on Snapchat, entitled “Burfffdayy Queennn,” the Bajan pop princess appeared at ease as she danced and twerked to Fetty Wap’s “My Way.” Wearing a sexy silver dress, Rihanna was in good spirits as she held a large glass of red wine.

Despite the good times, the last few weeks have been troubling for the “Anti” singer.

At the last minute, she backed out of her Grammy performance citing illness.

“Based on Rihanna’s examination, after Grammy rehearsal today, Rihanna’s doctor put her on vocal rest for 48 hours because she was at risk of hemorrhaging her vocal chords,” her rep told Page Six.

There’s also trouble ahead of her upcoming tour, which was postponed by two weeks. According to People, eight concert dates slated for May were rescheduled and two concerts in the U.K. were nixed.
