British trip-hop star Tricky was left mortified by his disastrous collaboration with Beyonce at Glastonbury Festival last year (11), branding it the most embarrassing moment of his life.
The former Massive Attack star joined the singer onstage during her headline set at the iconic U.K. event last year but their duet of Baby Boy fell flat when problems with Tricky's microphone left him barely audible.
The Crazy in Love hitmaker tried to revive their performance by grinding up against Tricky while singing her lines - but he cringes every time he remembers the incident.
He tells The Independent, "I'm really shy. I've never been so embarrassed. My body just froze. And it's like the whole world looking at you and waiting. God, I didn't want that to happen."
