James Packer in Mariah’s World “outtakes”

First footage of James Packer and Mariah Carey in upcoming E! reality series Mariah’s World has emerged in the US.

The Aussie billionaire can be seen celebrating with cake and champagne in outtakes obtained by Page Six.

In recent weeks the two have been the subject of headlines reporting a split, just weeks out from the series launch that sees Carey preparing for her nuptials.

A spokesperson for Packer’s company previously told Page Six that “he is not involved in any reality-TV program.”

An NBCU spokesperson has previously told TV Tonight James Packer would be appearing, but has not confirmed how prominently.

The E! series is due in December.
