Oprah Winfrey has denied rumours that Mariah Carey was set to announce she was pregnant on her U.S chat show.

The pop star was said to have been booked to appear on the show so she could share the news that she is expecting her first child with husband Nick Cannon.

But Oprah’s rep insists there are no such plans for Mimi to appear.

Meanwhile, the singer’s spokesperson has blasted reports that Mariah is pregnant.

Mariah has been plagued by baby rumours ever since her surprise wedding to actor/model Nick in April.
