After a seven-week break Rihanna is back on tour but her fans were less than pleased with her first performance, Radar Online reports. The "Stay" singer was in Singapore for a F1 concert at the Grand Prix on Sept. 22 and even though "Rihanna Navy" was more than excited leading up to the performance, she didn't wow the audience like she normally does.

Fans immediately took to Twitter to complain about the show. Some people said she showed up late, was lip-synching and looked like she was "high."

"Rihanna is lip-synching. From the Ex-soundman next to. Plus, right light isn't on, on her mic," one user tweeted.

Check out some of the reactions below:

Some users tweeted that the performance was so bad that fans were leaving the concert early.

"15% of the crowd either doesn't like #Rihanna, or realized that it's Monday tomorrow... So many people leaving!" @charmainephua tweeted.

Not everyone was upset with Rihanna's performance. Justin Bieber made an appearance at the show and tweeted to the pop star telling her how much he enjoyed himself.

This definitely isn't the first time the singer has been accused of putting on a pretty bad show. According to Radar back in July fans complained that Rihanna was "wasted" and "totally drunk" during a Poland concert.

She is also infamously known for showing up several hours late to her concerts and leaving her fans waiting.

"Delays of more than two hours are increasingly the standard at any Rihanna show this summer," Radar writes.

Reportedly at another concert in Gdynia fans were so upset that she left them waiting for 50 minutes that they began chanting "Beyonce" when she finally showed up.
