Super producer DJ Mustard signed with Roc Nation last April, but his first interaction with now boss Jay Z didn't go as expected. It ended with Hov getting the dial tone from the Cali beat maker, by mistake, of course. Mustard recently chopped it up with on Power106's Big Boy's Neighborhood and revealed how his disbelief caused him to hang up on one of the biggest rappers of all time. "He called, matter of fact, he E-mailed," said Mustard of the first correspondence he ever received from Jigga. "He was like, 'Yo, this J as in Z, do you have time to talk?' I'm like, what? I'm looking at the E-mail like...So I showed my girl like,'Yo, you see this?'

After giving in to his curiosity, he sought his manager for confirmation. "I was like, 'What's Jay's E-mail?,' he said. "He was like, whatever it was. I was like, damn this is the same E-mail. So I hit [the E-mail address] back like, 'Yup.' And like two seconds later he called. I'm like, 'Hello.' He like, 'Yo, this Jay.' I'm like, 'No it aint,' click."
