Jay-Z has put to the rest the rumours that his pop star wife Beyonce is pregnant.

The rapper spoke about the allegations during an appearance on radio station BBC 1Xtra.

"No. It's not true' first of all. But imagine that. I couldn't even fathom that,” Jay-Z said.

“But this is the fifth time they've done this. I wonder when the people are going to say, 'OK. We've done this four times already."

The couple married in April 2008 after meeting eight years earlier whilst dueting on single 'Bonnie and Clyde.'

This is not the first time to his wife has been reported to be pregnant – and Jay-Z said that the media wouldn't be the first to hear if the couple were expecting a baby.

“I have five kids, if you let them tell it, so it's the fifth time,” he said. “When that happens I'll let everyone know. I definitely would not let the papers know before anybody else.''

Jay-Z is currently promoting his new memoirs, Decoded.
