The singer said that she rewards adopted sons Wyatt, four, and 12-month-old Levi if they are to be adventurous with their food.
She told the Daily Mail, 'I'm all about bribery when it comes to my little kids eating, particularly my four-year-old: 'If you'll try this, Wyatt, you can have some of this.' That's how we do it.'
The 49-year-old added that she did struggle when it came to laying the law down with her sons, but was reassured by some motherly advice.
She explained, 'My mum said it's going to hurt you a lot more than it's going to hurt them.
'When I would get upset about putting him in a time-out or being stern with him as Wyatt was going through the terrible twos and challenging threes, she would say, 'Those things are not going to be memorable for him.'
'What's memorable for him is gonna be the feeling of safety.'
