Robbie Williams shocked guests at his BBC 1 concert taping on Sunday night when he shouted “screw you” before singing ‘Sexed Up’, a bitter song about ex-love Nicole Appleton.

“Robbie has dusted it off again because it’s his way of getting back at Nicole. He was devastated when she told the world she had aborted his baby” an insider revealed.

“It was something they had gone through together and it was very personal. She betrayed him and he can’t forgive her. That is why he is releasing the song on ‘Escapology’. It’s his turn to get even.”
