Sarah Graham, a former CBBC presenter, has thanked Robbie Williams for helping her with drug problems.

The former children's presenter said that she had been addicted to ecstasy and cocaine and very unhappy before Robbie Williams made her face herself and admit that she needed help.

Graham said that she had not discussed her drug problem with anyone before she met the singer in a London nightclub in 2001. There Robbie, who has himself battled problems with drink and drugs told her to go and seek help for her problems.

She then quit her job and went straight into rehab to quit abusing the substances.

She told The Sun: "Robbie was the first person I admitted my problem to.

"We met through friends and he was the only person I knew who had been through rehab."
