Chris Tarrant is gearing up for a special celebrity edition of 'Who Wants To Be a Millionaire' where some famous faces will appear alongside their mothers.
Speaking to ITV1's Daybreak he described how it can make celebrities act quite differently, adding it can often "feel quite weird".
Samantha Womack - who played baby-snatch mum Ronnie Mitchell on Eastenders - is among those taking part.
The actress will appear with her mum Di on Sunday.
Other celebrities to take part in the ITV1 programme are Benidorm star Steve Pemberton and Coronation Street's Anthony Cotton.
Chris Tarrant also revealed that some celebrities have turned down the chance to appear on the show in case they find the questions too difficult.
'Who Wants To Be A Millionaire' has been running on ITV for 14 years and the format is shown in more than 100 countries around the world.
You can watch it this Sunday at 8.30pm on ITV1.
