Fans took to social media to express their shock at the amount of empty seats.
The pop star still performed, however, it wasn’t received well by some members of the audience.
The 28-year-old is currently working through her ANTI World Tour, which bears the same name as her album that was released earlier in the year.
She had recently broken down during another concert in Dublin. Tears rolled down her cheeks as she sang ‘Love The Way You Lie’.
This also prompted fans to come to her aid.
After the emotional concert and the abundance of worried messages, Rihanna shared a video on Instagram with the caption, ‘What a night!!!! Such an emotional show for me! I feel so lucky to have a team like the #Navy man! I'm blessed!! No matter what I'm on you always snatch me out of it! I'm so grateful to have y'all! ⚓⚓⚓ #DUBLIN#ANTIWORLDTOUR’.
