Rihanna and Eminem's new video for the track Love The Way You Lie has broken the online record for the number of views in its first day.
In the first 24 hours it was watched by 6.6 million people on the web.
It features Hollywood actors Megan Fox from Transformers and Dominic Monaghan who was in the Lord Of The Rings films.
Eminem raps about a violent relationship and Rihanna said: "It's something that I understood, something I connected with."
Rihanna was hit by her ex-boyfriend Chris Brown last year before an award ceremony.
He publicly apologised saying that he had been brought up in a home where there was domestic violence.
Eminem has written songs before about domestic violence
He was told to do 180 community service hours doing things like picking up litter and cleaning the streets.
Rihanna says when Eminem asked her to duet with him on Love The Way You Lie she immediately wanted to do it.
She said: "He pretty much just broke down the cycle of domestic violence and it's something that people don't have a lot of insight on."
The rapper has written songs before about his difficult relationship with his ex-wife.
