Appearing on the Jimmy Kimmel Live show yesterday, the Hollywood actress, who found fame as Lizzie McGuire, explained, 'The first time I was here on your show I signed my first body part.
'Some kid said, 'Can you sign my arm?' I'm like, 'Whatever, I've signed weirder than that.'
'He went and got it tattooed while I was doing your show, in Hollywood. At the end when I walked out to get in my car he showed me his arm and it's all pink and bubbly because he had my name tattooed on his arm.'
She added, 'I was like, 'that is dedication and please, I really don't need your mother calling and screaming!''
