It's the biggest battle in music since Fiddy versus Kanye. All the kids are talking about it. And the adults. And some small animals.
But just in case you've not heard, there ain't no love between Eamonn Holmes and Rihanna anymore. In fact, it doesn't sound like there was a lot in the first place, with Holmes saying now that he'd like to give the singer a slap and make her "wise up". But only if she was his daughter.
Apparently slapping young women and shouting at them when you're not a blood relation is frowned upon, particularly on TV.
The Sky News presenter told Star magazine: "I find the entourages that some people come with, especially the Americans, really pathetic. Rihanna, for example, is a beautiful girl, but if she was your daughter, you'd give her a slap and tell her to wise up. She is surrounded by people who treat her like a little flower".
To be fair, he does actually have a point. Are you a parent of a pop star who is surrounded by yes men? Start slapping now.
