The husband and wife team presented UK TV show 'This Morning' today (23.08.13) and Rochelle made her confession during a segment on women trying to change their husbands or partners.
Rochelle said: ''My pet hate when we started going out was that he'd always show off his man cleavage.''
Marvin interjected, saying: ''You didn't say that when we got together - you were happy with it.''
But Rochelle admitted: ''I loved you but it was all a little bit too much for me!''
Marvin saw the funny side of his wife's comments but then confessed his pet hate of her - the excessive luggage Rochelle takes away on trips.
The 'Beat Again' singer - who has three-month-old daughter Alaia-Mai Humes with the 'What About Us' hitmaker - confessed: ''I wish Rochelle would take less hand luggage when we go away. She always packs far too much.''
