Cowell's family was "heartbroken" when Julie passed away on Sunday (05Jul15) after suffering a stroke, aged 89, and the talent show creator postponed the start of filming on the TV series on Monday (06Jul15).

The try-outs will now start on Wednesday in Manchester, England and a spokesman for Cowell's company Syco Entertainment confirms the TV mogul will attend the sessions along with fellow judges Rita Ora, Cheryl Cole and British DJ Nick Grimshaw.
