Janelle Monae didn't like the audience at Coachella Valley Music and Arts Festival.

The 'Tightrope' singer joined Outkast on stage to sing with Big Boi at the event in Indio, California last month, and while critics claimed the show failed to live up to expectations but Janelle blames the crowd.

She told Faster Louder: ''I didn't like that Coachella audience.

''I'm happy I got to CounterPoint [Music Festival] in Georgia, because those were real festival-goers, in my opinion.''

Janelle joined Andre 3000 at the CounterPoint Music Festival to dance on stage during 'Hey Ya!' last weekend and gushed about the band who have reunited onstage after a near decade-long hiatus.

She said: ''That is my favourite duo, favourite rap group ever invented.

''They were in their time travel machine and they came back to see us, and I think we should all be grateful that they came back. ''The music is more fun, and lives are enriched with those two ATLiens performing. They're also great friends of mine, so it's great to see your friends do what they love doing and get the love and support they need.''

Outkast collaborated with Monae on two tracks from their most recent album - 2006's 'Idlewild' - and she also made an appearance on Big Boi's 2010 solo album 'Sir Lucious Left Foot: The Son of Chico Dusty'.
