The 35-year-old former Lothario has reportedly vowed not to follow in Cheryl Cole and Dannii Minogue's footsteps and break down.
An insider told the Daily Star, 'Piers knows how to push people's buttons but Russell just says, 'Bring it on!' He's not worried about anything he wants to ask him and he's determined he won't cry like some of the other guests.
'Piers may need to watch out, Russell's sense of humour could see the tables turned on him.'
And he is rumoured to be planning to hit back at Rod Stewart after he rubbished Russell's claim that he slept with 90 women in one month.
The source added, 'I'm sure Russell will have a few digs of his own to get back at Rod. His interview will be captivating TV.'
