Swift, 25, has accumulated a group of famous celebrity friends, many of whom have joined her on stage on her `1989` world tour but Rihanna, 27, says she has no plans to do the same as their "brands don't match", reports femalefirst.co.uk.
Asked if she would tour with Swift, Rihanna told NME magazine: "I don't think I would. I just don't think it makes sense. I don't think our brands are the same. I don't think they match, I don't think our audiences are the same. In my mind, she's a role model, I'm not."
