Rihanna broke down in tears during her concert in Dublin last night after arriving 30 minutes late on stage.
The singer became emotional as she started singing the Eminem collaboration track, Love The Way You Lie.
Fans have taken to social media to post videos and pictures of the gig and express concern over what happened.
Rihanna gave no explanation as to why she got upset, other than a message on Instagram.
“What a night!!!! Such an emotional show for me!” she wrote.
“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”
It happened on the first night of the UK and Ireland leg of her ANTI World Tour which heads to Wembley on Friday.
As she launched into the track, she can be seen turning away from the camera as she lifts up her hands to signal for a moment to compose herself.
