Cat Deeley was left red-faced after a string of blunders forced Bob Geldof to step in and correct her on Tuesday’s This Morning.

As Cat and co-host Andi Peters spoke to Bob and Midge Ure about Band Aid, Cat made a slew of factual mistakes.

When Cat told viewers that Band Aid had raised almost £2million, Bob quickly corrected her that it was actually £480million.

He joked: ‘You’ve never done this before?’

Cat said: ‘Never, I’m a spring chicken!’

If that weren’t awkward enough, Bob was forced to correct Cat for a second time, swiping: ‘Are you doing your research?’

He fumed: ‘Who briefs you? Who does your research?! Deeley. It’s BBC Four for god’s sake.’

Andi quipped: ‘Oh no, shamed by Bob Geldof live on telly, I love it!’

Despite Cat’s mistakes, the hosts and Bob got on like a house on fire as they laughed off the blunders.

Speaking about the documentary, Bob said: ‘That Sunday morning when a bunch of young spotty English pop stars who were (more or less) just out of school and had taken over the pop culture of the world.
