The Vaccines have suggested Rihanna lacks artistic merit because she does not write her own songs.
The band also suggested Coldplay would do anything to be the biggest band in the world.
The Vaccines guitarist Freddie Cowan told Digital Spy: "Rihanna isn't an artist - she has 15 writers, 15 songwriters and 15 producers all fighting for space on her albums and she's the face of it."
"I have nothing against it, but I don't want to be associated with it," he added.
Coldplay are due to perform their collaboration with Rihanna, "Princess Of China", at the Paralympics closing ceremony next month, and the guitarist suggested the song lacked "artistic merit" - although he admitted he had never heard it.
"I've never heard that song, but it's Coldplay - they'll do whatever they can to be the biggest band on earth, to be bigger than U2," he said.
"They Do It Really Well And They'Ve Never Put Out a Bad Album So Hats Off To Them," he continued. "I have nothing against those collaborations because I don't feel you can judge people, but I don't think I'll ever be involved in something like that." "It needs artistic merit," he said.
The Vaccines are set to release their new album "Come Of Age" on 3 September.
The band recently announced their biggest headline UK tour to date, playing 11 shows in November - check Gigwise Gig Tickets for more information.
