The ex-Take That singer, 35, has been spending money to keep the twins in the competition.
'I do love them I voted for them three times over the weekend,' he said.
Robbie says he can relate to the boys, 18, collectively known as Jedward.
'I know how they will feel inside, like the whole world hates them,' he told Fearne Cotton on her Radio 1 show.
'They are just two kids; it's not their fault they are there.'
