The 'Birthday Cake' singer joked that she takes it personally if people criticise the 'Rolling in the Deep' hitmaker.
"Well, who doesn't like Adele?" Rihanna told OK!. "Honestly, if I find somebody who doesn't like Adele there will be trouble."
She added: "I'd take that very personally!"
The 'You Da One' star has previously spoken of her "affection" for Adele in the past, but added that she can no longer listen to the "depressing" 21 album.
Rihanna recently sparked criticism and debate among fans after she posted a photo of herself partying at the Coachella festival with what appears to be some kind of white powder.
Adele returned to the top of the UK album chart for the 22nd week with 21 at the weekend after 64 weeks inside the chart.
